Which of the following is a bioethical concern of the Human Genome Project?

Humans may try to create "designer babies"

What unique property of stem cells make them so desirable for therapeutic use?

They can develop into many different cell types

Several procedures involved in the creation of a transgenic organism are listed. 1. A specific gene is identified in DNA. 2. The DNA fragment is placed in a plasmid. 3. The DNA fragment of interest is isolated. 4. The plasmid is transferred to a bacterial cell. 5. A plasmid is cut by a restriction enzyme.

1,3,5,2,4

Which is a step in the process of producing transgenic bacteria?

A human gene is inserted into a bacterial plasmid.

Which of the following best describes the Human Genome Project?

A project that mapped the genes of a human, allowing individuals to be tested for certain genes that cause genetic diseases and to develop gene therapies

Which of the following is NOT true of a restriction site?

A restriction site is found on a restriction enzyme.

Which of the following best explains why DNA fingerprints can be used to identify an individual, such as from a crime scene sample?

Each individual has a unique DNA sequence, with the exception of identical twins

What is an argument for using embryonic stem cells over adult stem cells?

Genetic engineering means

Modifying DNA by adding or removing genes

Which is a true statement about gel electrophoresis and DNA fingerprinting?

Over time, the shorter/ lighter strands of DNA will move faster through the gel, causing them to move further down toward the bottom of the gel.
