1. DNA (deoxyribonucleic acid)
The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pair s of nucleotide s. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T). In nature, base pairs form only between A and T and between G and C; thus the base sequence of each single strand can be deduced from that of its partner.

2. DNA annealing
The sticking together ( renaturing ) of complementary single strands of DNA to make a double-stranded DNA after the strands have first been pulled apart ( denature d). This involves forming hydrogen bond s between the base pair s.

3. DNA diagnosis
The use of DNA polymorphism s to detect the presence of a disease gene .

4. DNA duplex
The double-stranded DNA molecule, which has a double helix (usually "right-handed") structure.

5. DNA excision
The removal of a damaged segment of a DNA molecule by a group of DNA repair enzyme s in order to repair the molecule.

6. DNA filter assay
A lab technique used to identify the complementary base sequence s of DNA . It involves immobilizing the DNA on a filter and putting it in a solution that contains radioactively-labeled probe DNA or RNA molecules.

7. DNA fingerprint
The unique pattern of DNA fragments identified by Southern hybridization (using a probe that binds to a polymorphic region of DNA) or by polymerase chain reaction (using primer s flanking the polymorphic region).

8. DNA fingerprinting
A lab technique that compares the patterns of bands on analogous DNA fragments from two or more separate individuals; this is done to find out how closely related they are to each another.

9. DNA footprinting
A lab technique that uses gel electrophoresis to find out which parts of a DNA molecule have sites for protein s to attach to them. The technique compares DNA which has been in the presence of DNA binding proteins with DNA that is "pure."

10. DNA gene
Any of a number of gene s found in the bacteria Escherichia coli which makes protein s that are essential for DNA replication .
