MCQ on RNA Polymerase with Answers (PDF)

RNA polymerase is an enzyme that synthesizes RNA from a DNA template during transcription. It binds to specific regions of the DNA called promoters and unwinds the DNA strands to read the sequence. RNA polymerase then assembles complementary RNA nucleotides to form a single-stranded RNA molecule. This RNA serves as a template for protein synthesis or other functions in the cell. RNA polymerase is essential for gene expression and cellular function. This is an MCQ on RNA Polymerase with Answers. You can download all these questions as PDF from the results page of this quiz.
