DNA

 
complementary DNA (cDNA) (copy DNA (cDNA)) synthetic DNA transcribed from a specific RNA through the reaction of the enzyme reverse transcriptase.

com·ple·men·ta·ry DNA (cDNA),

1. single-stranded DNA that is complementary to messenger RNA;
2. DNA that has been synthesized from mRNA by the action of reverse transcriptase.
