A)Repeating the test in different areas of the DNA ensures that the investigator did not make any mistakes in determining the DNA sequence.
B)Most regions of the human genome are identical, so you have to look in many locations to make sure you find a region that shows differences.
C)The more regions of the DNA you examine, the less likely you are to run into a coincidental similarity between DNA sequences.
D)Restriction enzymes only work in these 13 regions of the human genome.

A)identifying the location of genes that cause genetic disorders within the human genome
B)finding a way to direct recombinant viruses to specific cells and/or locations in the genome
C)determining the DNA sequence of the genes that cause genetic disorders
D)finding a way to get recombinant DNA into human cells

A)transfer a gene to a specific cell in the body.
B)separate DNA fragments from one another.
C)probe DNA for faulty genes.
D)attach DNA fragments to one another.
