Question

3 multiple choice 20 points what is the main purpose of transcription in cells? to turn proteins back into dna to string together amino acids into a protein to produce a molecule of rna from a strand of dna to produce a strand of dna from a molecule of rna

Explanation:

Transcription is the process in which a DNA - dependent RNA polymerase uses a DNA strand as a template to synthesize a complementary RNA molecule. It is not about turning proteins back into DNA (reverse - transcription of RNA to DNA is a different process), nor is it stringing amino acids into a protein (which is translation). And it is not producing DNA from RNA (reverse transcription).

Answer:

To produce a molecule of RNA from a strand of DNA
