The study of the proteins that result from an organism's genome is called

Proteomics

DNA fingerprinting can be used to

Prove a family relationship

The main role of primers during the PCR process is to

Provide a starting point for DNA synthesis.

DNA that contains genes from more than one organism is called

Requires primers and nucleotides

Bacterial enzymes that cut the DNA of viruses

Restriction enzymes

The goal of gene therapy is to replace defective or missing genes in order to

Treat some genetic disorders

Scientists use PCR to primarily

Gene sequencing defines the order of

DNA nucleotides in genes or genome o

Some restriction enzyme leave behind sticky ends, or tails of

Exposed bases

Which technique is used to seperate DNA fragments by their size

Gel e😈electrophoresis

Which of the following are examples of clones

Identical twin sisters

The two main goals of the human genome project are to sequence all of the DNA base pairs of the human chromosomes and to

Identify all of the genes within the genome.

During the PCR cycle wat happens to the number of copies of the DNA segment.

It doubles

Which phrase is true for a DNA fingerprint

It is a type of restriction map

The patterns of bands on a DNA fingerprint shows the sizes of DNA fragments related to the

Number of repeat sequences

DNA microarrays can be used to compare different cell types by showing

Patterns of gene expression.

Suppose a segment of DNA contains 5 restriction sites for a particular restriction enzyme. How many fragments of DNA will remain after the enzyme is used to cut out the DNA.

Six nitch

What to the bands on a restriction map show

Sizes of DNA fragments

Which factor has so dar kept gene therapy from becoming an effective treatment for genetic disorders?

The difficulty of getting new genes to become part of a cell's DNA.

Which statement is true of all genetically engineered organisms?

They have altered genomes

How are viruses used in gene therapy

To carry new genes into cells

The first step of PCR is too heat a DNA molecule to more than ninety degrees. What is the function of this step.

To separate DNA strands

Plants that contain recombinant DNA are called

Transgenic
