Reverse transcriptase may be a DNA polymerase enzyme that transcribes single-stranded RNA into DNA.
What is reverse transcriptase?
- This enzyme is in a position to synthesize a double-stranded DNA into a single-strand DNA once the RNA is transcribed in 1st step.
- Found in retroviruses, like the human immunodeficiency virus (HIV).
- Reverse transcriptase is used to form a cDNA copy of the mRNA.
- The cDNA sample is then amplified by PCR. This yields multiple copies of cDNA without introns
Thus, we can conclude that the correct option is D.
To make cDNA is the role of reverse transcriptase in DNA technologies.
