Chimeric reverse transcriptase
WebReverse transcriptase is an RNA dependent DNA polymerase (it requires RNA as a template to synthesize cDNA). The RT identifies and binds the RNA to synthesize single stood RNA (ssRNA). After synthesizing the cDNA, RT cleaves the RNA and start synthesizing double-stranded DNA (dsDNA).
