In genetics, complementary DNA (cDNA) is DNA synthesized from a mature mRNA template in a reaction catalyzed by the enzyme reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes. cDNA is also produced by retroviruses (such as HIV-1, HIV-2, Simian Immunodeficiency Virus, etc.) which is integrated into its host to create a provirus. Overview The central dogma of molecular biology outlines that in synthesizing proteins, DNA is transcribed into mRNA, which is translate… (More on Cdna)
