Complementary DNA

In genetics, complementary DNA (cDNA) is DNA synthesized from a mature mRNA template in a reaction catalysed by the enzyme reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes.

Noun
1. single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase
(synonym) cDNA
(hypernym) deoxyribonucleic acid, desoxyribonucleic acid, DNA

DNA made from a messenger RNA template. The single-stranded form is often used as a probe in physical mapping.

(cDNA): Single-stranded DNA produced from an RNA template (usually mRNA) by reverse transcriptase in vitro. It lacks the introns present in corresponding genomic DNA.
