<P> In genetics , complementary DNA ( cDNA ) is DNA synthesized from a single stranded RNA ( e.g. , messenger RNA ( mRNA ) or microRNA ) template in a reaction catalyzed by the enzyme reverse transcriptase . cDNA is often used to clone eukaryotic genes in prokaryotes . When scientists want to express a specific protein in a cell that does not normally express that protein ( i.e. , heterologous expression ) , they will transfer the cDNA that codes for the protein to the recipient cell . cDNA is also produced naturally by retroviruses ( such as HIV - 1 , HIV - 2 , simian immunodeficiency virus , etc . ) and then integrated into the host 's genome , where it creates a provirus . </P>
