Propolis Cognitive Error Autopsy

Official Correct Choice:
Option C: RNA polymerase
Concept:

Enzymes in the central dogma are named directly for the polymer they synthesize (build).

Solution:

  • Transcription is the biological process of reading a DNA blueprint to build a complementary messenger RNA (mRNA) strand.


  • The massive enzyme responsible for prying the DNA apart, reading the template, and stitching together the new RNA nucleotides is RNA polymerase (specifically, it polymerizes RNA).


Why other options are incorrect:

  • DNA polymerase: Synthesizes new DNA during cellular replication, not transcription.


  • RNA dependent DNA polymerase: Also known as Reverse Transcriptase; used by retroviruses (like HIV) to turn RNA back into DNA.


  • RNA transcriptase: A mostly fabricated/colloquial term not used in formal biochemistry (the actual enzyme is RNA polymerase).

Quality & Fidelity Assurance: Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
