Mutations in mitochondrial DNA may contribute to the loss of neurons in
Alzheimer's and Parkinson's disease and has been associated with diabetes, autism, and a variety of metabolic disorders
When more than one gene is involved, environmental factors such as the changes caused by aging, smoking, exposure to environmental toxins, or other factors, may trigger the onset of a genetic disease, as in cases of
Alzheimer's disease, diabetes, obesity, and some forms of cancer
Generally, couples can adopt a child of different race. Adoptions of Native American children, however, are governed by the Indian Child welfare act, and the act provisions outline specific rules and procedures that must be followed if the adoption of a Native American child is to be
Approved
Legally, the legal rights of newborns Are the same as those of any other American citizen of any age. For newborns who are severely disabled, however, existing law provides for several treatment options. Under the federal child abuse amendments, if the parents agree, physicians may legally withhold treatment, including food and water, from infants who
Are chronically and irreversibly comatose. Will most certainly die and for whom treatment is considered futile. Would suffer inhumanely if treatment were provided.
This process involves the mechanical injection of viable semen into the vagina.
Artificial insemination
Laws in some states give minors the right to consent to general medical and surgical care under some circumstances such as
Being a parent themselves, being pregnant, or reaching a certain age.
Family history is often one of the strongest risk factors for common disease complexes such as
Cancer, cardiovascular disease, diabetes, autoimmune disorders, and psychiatric illnesses
This type of testing is offered to individuals who have a family history of a genetic disorder and to people in certain ethnic groups with an increased risk of specific genetic conditions. It is used to identify people who carry one copy of a gene mutation that, when present in two copies, causes a genetic disorder.
Carrier testing

Used to identify or rule out a specific genetic or chromosomal condition or to confirm a diagnosis when a particular condition is suspected based on physical signs and symptoms. Testing may be done at any time during a persons life, but it is not available for all genes or all genetic conditions.
Diagnostic testing
It is estimated in the United States that about 10 to 15% of reproductive age couples will have

Scientist manipulate DNA within the cells of plants, animals, and other organisms to ensure that certain advantageous traits will appear and be passed on and that certain harmful traits are eliminated. This is called
Genetic engineering
Traditional surrogacy differs from gestational surrogacy and that a traditional surrogate is
Genetically related to the fetus she carries
The science that accounts for differences and resemblance among people and other organisms related by descent
Genetics
Involves the correction of an abnormality in the genes of a sperm or egg but is presently considered an inappropriate way to deal with genetic diseases because of ethical issues, cost, lack of research in humans, lack of knowledge about whether or not the changes would be maintained in the growing embryo, and the relative ease of treating the pertinent conditions somatically when needed
Germ-line gene therapy
If the surrogate is not genetically related to the embryo, the type of surrogacy is called
Gestational surrogacy
Other stem cell cultures are grown specifically for research purposes and are scrutinized through
Government regulation

Heredity
If the partner sperm cells are not viable, a donor sperm may be used to fertilize the woman's eggs during artificial insemination and this is called
Heterologous artificial insemination
If a man's sperm cells are used to fertilize his partners eggs during artificial insemination the process is called
Homologous artificial insemination
Adopting parents locate a birth mother or vice versa and then ask an agency to take over the adoption process. Prospective parents can find a birth mother willing to give up her child and can bypass the long waiting list most agencies maintain for adoption and can perhaps be better assured that the adoption will proceed in an orderly and legal fashion.
Identified adoption
Does the minor live at home with parents or other supervising adults, or is he or she living independently? If living at home, does he or she pay for room and board? Does the Miner have a job, and does he or she spent his or her earnings without parental supervision? Does the minor pay his or her own debts? Is the minor claimed as a dependent on the parents tax return?
Important factors to be considered before a judge will issue an emancipation order
In this process, eggs and sperm are brought together outside the body in a test tube or petri dish. When fertilization takes place, the resulting embryo can then be frozen in liquid nitrogen for future use or implanted in the female uterus for pregnancy to occur.
In vitro fertilization (IVF)
Arranged without the involvement of adoption agencies. Potential adoptive parents may hear of a mother who wants to give her child, or they may advertise in newspapers or on the Internet to find such a mother. At some point in the process, an attorney must be involved to ensure the legality of the adoption. A few states prohibit and it is strictly regulated in states that do allow this form of adoption.
Independent or private adoption
The failure to conceive for a period of 12 months or longer due to a deviation from or interruption of the normal structure or function of any reproductive part, organ, or system.
Infertility
Occur when couples adopt children who are citizens of foreign countries. In these procedures, adoptive parents must not only meet requirements of the foreign country where the child resides, they must also meet all the US state requirements and US immigration and naturalization service rules
International adoption
In many states, minors seeking an abortion must involve at least one parent in the decision. This means that teenagers who do not tell their parents about a pregnancy must either travel out of state or obtain approval from a judge a process known as
Judicial bypass
Individuals in their mid to late teens who are considered mature enough to comprehend a physicians recommendations and give informed consent
Mature minors
Most states allow them to seek medical treatment without the consent of a parent or guardian in certain critical areas, such as mental health, drug and/or alcohol addiction, treatment for sexually transmitted diseases, pregnancy, and contraceptive services
Mature minors
Several states also allow minors who are parents to consent to medical care for their children. In many states, mothers who are minors may also legally place their children up for adoption without the consent or knowledge of the
Mother's parents
Diseases can also result from mutations in mitochondrial DNA, which multicelled organisms inherit mostly from
Mothers
Those found in adult blood forming tissue, can become only a limited number of types of tissues and cells in the body
Multi potent stem cells
This testing is used after birth to identify genetic disorders that can be treated early in life. Two examples are phenylketonuria urea and congenital hypothyroidism
Newborn screening
To date, animal cloning does not always yield viable offspring, with only one or two healthy animals resulting from approximately every 100 experiments. Not only do most attempts to clone mammals fail about 30% of clones born alive are affected with large offspring syndrome and other debilitating conditions. Scientist do not yet understand the process involved in reproductive cloning well enough to ensure success, and a large failure rate in human clones is unacceptable. Like Dolly the sheep, many animals have died prematurely from infection and other complications the and same problems would be expected to occur in human cloning. Scientists do not know how cloning could impact mental development. While factors such as intellect and mood may not be important for a cloned cow or mouse, they are crucial for development of healthy humans
Objections to human cloning based on animal biology and physiology
The state may act as a parental authority. This doctrine is the legal principle that grants the state the broad authority to act in the best interest of the child, sometimes overriding parental decisions, and allows the state to remove abused or neglected children from the custody of offending parents.

Phosphate group, a sugar group, and a nitrogen base
Found in embryonic tissue, can become almost all types of tissues and cells. Such cells have shown promise for treating patients with a wide variety of medical problems, such as Parkinson's, Alzheimer's, diabetes, strokes, burns, spinal cord injuries, and other neurological disorders.
Pluripotent stem cells
This type of testing is used to detect gene mutations associated with disorders that appear after birth, often later in life. These tests can be helpful to people who have a family member with a genetic disorder, but who have no features of the disorder themselves at the time of testing. Predictive testing can identify mutations that increase a persons risk of developing disorders with a genetic basis, such as certain types of cancer.
Predictive and pre-symptomatic testing
Is a specialized technique that can reduce the risk of having a child with a particular genetic or chromosomal disorder. It is used to detect genetic changes in embryos that were created using assisted reproductive techniques such as in vitro fertilization
Preimplantation testing, also called preimplantation genetic diagnosis (PGD)
The adoption assistance in child welfare act of 1980, the child abuse prevention and treatment and adoption reform act, and the Indian Child welfare act all contain

Relative adoption
RNA comes into play when DNA
Replicates itself
Which produces copies of entire animals
Reproductive cloning
In some states, the baby can be handed over to a doctor or police officer, or left at a fire station or hospital
Safe haven laws
Most states place limits on the ages of children who can be abandon without prosecution for two reasons. To encourage parents determined to abandon their children to do so early, while the children can receive adequate nutrition and medical care, and to prevent situations that occurred when Safehaven laws were new in which parents have a abandoned problem children of all ages to the care of the state.
Safe haven laws
Most states specify which locations are considered safe havens to prevent parents from leaving infants on the step of empty churches or in other locations where discovery and emergency care are unavailable
Safe haven laws
Required under most state laws, to take the child into custody, provide medical care as necessary, and inform the abandoning parent, if possible, that he or she is relinquishing the child for adoption. Some state laws also require safe haven providers to try to determine the identity of the non-relinquishing parent and to attempt to learn family and medical history
Safe haven laws
Some states do not entirely eliminate prosecution but will allow reduction in charges
Safe haven laws
Some states, the parent can remain anonymous, while in others, he or she must reveal their identity and give a medical history. In some states, medical history can also be dropped off anonymously
Safe haven laws
Depending on the state law, both married and unmarried couples may adopt, and single people may adopt through a process called
Single parent adoption

Surrogacy
Offers some protection against genetic discrimination in the workplace. It protects against discrimination those who have a genetic condition or disease, or are regarded as having a disability.
The Americans with disabilities act of 1990
The standard is used in child placement situations. It is also used when we legal authorities must work with healthcare practitioners to determine the least harmful and most appropriate treatment for an ailing child
The common standard is "best interest of the child." In other words which alternative will be the best safeguard for the child's growth, development, and health
They are self-supporting. They are married, provided the marriage is legal. In most states, persons must be at least 16 to Mary and those under the age of 18 must have parental consent. Emancipation is not forfeited if the minor divorces or separated or widowed. They are serving in the Armed Forces.
The court may declare minors emancipated if one or more of the following criteria are met
An act was passed in to law, prohibiting discrimination in the workplace and by health insurance issuers. In addition, there are other legal protections against genetic discrimination by employers, insurers of health insurance, and others.

Pairs of the bases, represented by the letters A, T, G, and C, make up the rungs of the helix ladder the order of these for chemical functions as an alphabetic code, allowing organisms to create long, _____________ codes.
double helix, complicated
Fortunately, an organism does not need to read and interpret the ________ DNA strand each time it needs to build proteins. Instead, the organism needs to access only a small part of the DNA, called a gene,to build a protein for which it carries the code. Some genes are only a few hundred base pairs long whereas others may be _________ ________ base pairs long.

The __________ __________ project, funded by the US government, was started in 1990 to analyze the entire human genome. Scientists around the world who worked on the project set out to map all of the genes within 23 pairs of human chromosomes. The project was scheduled for completion in 2003, but was 90% complete in 2001.
