Question 1.
As the fundamental unit of heredity, genes instruct the body cells to make proteins that determine everything from hair color to susceptibility of disease.

End of Question 1

Question 2.
The only arrangement possible in the double-helix configuration was the pairing of bases A to G and T to C, a concept that is known as complementary base pairing.

End of Question 2

Question 3.
The “Human Genome Project,” a project to determine the order of bases on all 23 pairs of human chromosomes, is expected to be completed by 2010.

End of Question 3

Question 4.
DNA replication was first accomplished using a technique known as polymerase chain reaction.

End of Question 4

Question 5.
Molecular biologists can cut DNA into fragments using restriction enzymes, which can later be incorporated into another strand of DNA.

End of Question 5

Question 6.
DNA technology is useful in identification because no two humans, except for identical twins, have the same type of tandem repeats in a strand of DNA.

End of Question 6

Question 7.
RFLP is a technique designed to copy or multiply DNA strands.

End of Question 7

Question 8.
The latest, most successful and widely used DNA profiling procedure is the short tandem repeat.

End of Question 8

Question 9.
Mitochondrial DNA is found outside the nucleus of the cell and is inherited solely from the mother.

End of Question 9

Question 10.
Unfortunately, an examination of DNA band patterns in the crime laboratory is not able to reveal the presence of contamination, thereby making the concern about contamination of a DNA-containing specimen crucial in the evidence collection process.
