Question

RNAP pincers clamp down on ---------.

(A) DNA template strand
(B) RNA primer
(C) Ribosomal RNA
(D) Transfer RNA

Answer 1

RNAP pincers clamp down on the DNA template strand during the transcription process to aid in mRNA synthesis.

Step-by-step explanation:

The role of the RNA polymerase (RNAP) pincers during the process of transcription. Specifically, it inquires about what the RNAP pincers clamp down on. The correct answer is (A) DNA template strand. During transcription, the RNAP tracks along the DNA template strand, synthesizes mRNA in the 5' to 3' direction, and at the same time unwinds and rewinds the DNA as it reads the sequence. The RNAP pincers are responsible for maintaining the correct positioning and movement along the DNA template strand to facilitate accurate RNA synthesis.
