Question

You are attempting to synthesize rRNA in a test tube using DNA isolated from mouse cells. In addition to the template DNA, ribonucleotides, and the necessary transcription factors, you should also add what enzyme to the test tube?a.poly-A polymeraseb.RNA polymerase IIIc.RNA polymerase Id.RNA polymerase II

Answer 1

d. RNA polymerase II.

Step-by-step explanation:

The main enzyme responsible for RNA synthesis is RNA polymerase, which catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) directed by a DNA mold.

Eukaryotic cells contain three types of nuclear RNA polymerases that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.
