Which action is one role of RNA polymerase during transcription? to produce a start sequence to switch uracil with thymine on the exposed gene to break down an already existing protein to build a molecule of mRNA

Respuesta :

Answer:

The correct answer will be option-to build a molecule of mRNA

Explanation:

The RNA polymerase is the enzyme which acts during the process of transcription which produces the transcript molecule of the gene called mRNA.

RNA polymerase as the name suggests help polymerise the RNA molecule from the DNA by copying the DNA sequence and adding specific complementary bases to form the mRNA molecule.

The RNA polymerase enzyme forms mRNA molecule once the enzyme binds the promoter sequence located upstream of the regulatory sequence of the gene.

Thus, the selected option is the correct answer.
