Question

what would be the direct result if rna polymerase were missing from a cell? a. mrna could not be translated. b. dna could not be transcribed. c. amino acids could not form polypeptides. d. mrna could not leave the nucleus.

Explanation:

RNA polymerase is essential for transcription. Transcription is the process of making RNA from DNA. Without RNA polymerase, DNA cannot be transcribed into mRNA. Option A (mRNA translation) depends on ribosomes, not RNA polymerase. Option C (polypeptide formation) occurs during translation. Option D (mRNA leaving nucleus) is about nuclear pore function, not RNA polymerase.

Answer:

B. DNA could not be transcribed.
