Where does RNA polymerase begin transcribing a gene into mRNA?

IrinaK [193]

Answer:

The correct answer will be option-B

Explanation:

The process of transcription transcribes the sequence of the bases of genes present on DNA to mRNA which acts as a messenger molecule for the protein synthesis.

The process of transcription is mediated by the presence of enzymes which includes the main transcription enzyme called RNA polymerase. RNA polymerase attaches nucleotides to RNA strand.

The transcription process initiates in three stages: initiation, elongation and termination.

The initiation process begins when RNA polymerase binds to the promoter nucleotide sequence which is present at the start site or the upstream on DNA towards 5' end.

Thus, Option-B is the correct answer.
