What is AT (in DNA)?

Amplification, DNA: The production of multiple copies of a sequence of DNA. Repeated copying of a piece of DNA. DNA amplification plays a role in cancer...

Antisense DNA: DNA normally has two strands, i.e., the sense strand and the antisense strand. In double-stranded DNA, only one strand codes for the RNA that is translated into protein....

Assembly, DNA: The process of putting fragments of DNA that have been sequenced into their correct chromosomal positions. The pieces of DNA are assembled to reconstitute the sequence of the...

Base in DNA: A unit of the DNA. There are 4 bases: adenine (A),guanine (G), thymine (T), and cytosine (C). The sequence of bases (for example, CAG) isthe genetic code....

Cloning, DNA: The use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA.

Coding DNA: A sequence of DNA that codes for protein. Coding DNA sequences are separated by long regions of DNA called introns that have no apparent function. Coding DNA is...

Complementary DNA: Single-stranded DNA made in the laboratory from a messenger RNA template under the aegis of the enzyme reverse transcriptase. This form of DNA is often used as a...

Did not attend (DNA): In the UK, DNA is an abbreviation for did not attend. (In the US, the term used for a patient who missed an appointment is no-show.)

Directed DNA sequencing: Successively sequencing DNA from adjacent stretches of a chromosome.
