During protein synthesis, what process uses an RNA strand to produce a complementary strand of DNA?
Correct answer
A
Rationale
The correct answer is transcription. Transcription is the process in which an RNA molecule is synthesized from a DNA template. During transcription, an RNA polymerase enzyme reads the DNA template and produces a complementary RNA strand, not DNA. This RNA strand is used as a template in translation to synthesize proteins, where the mRNA is read to produce a protein.
