Reverse transcription begins when the viral particle enters the cytoplasm of a target cell. The viral RNA genome enters the cytoplasm as part of a nucleoprotein complex that has not been well characterized.

Why is reverse transcription done?
Reverse transcriptase is used to make a cDNA copy of the mRNA. The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without introns. Reverse transcription followed by PCR allows cloning of genes starting from the messenger RNA, and thus, identifying the expressed exons of the eukaryotic gene.
What is reverse transcription and in which type of organisms does it occur?
Reverse transcription (which occurs in both prokaryotes and eukaryotes) is the synthesis of DNA from an RNA template. A class of RNA viruses, called retroviruses, are characterized by the presence of an RNA‐dependent DNA polymerase (reverse transcriptase).
Where does reverse transcription take place?
This reverse transcription takes place in virus producer cells since the addition of the RT inhibitor AZT prevented accumulation of viral DNA in virions, in agreement with the earlier findings of Pomerantz et al.
Which reaction shows reverse transcription?
Reverse Transcription Polymerase Chain Reaction
As a first step, isolated mRNA is converted to a complementary DNA (cDNA) molecule with an RNA-dependent DNA polymerase, also known as reverse transcriptase, during a process called reverse transcription.
