Question

which best compares dna and rna with regard to the process of protein production?
○ dna transforms from a nucleic acid into a protein, and rna remains a nucleic acid.
○ rna transforms from a nucleic acid into a protein, and dna remains a nucleic acid.
○ dna leaves the nucleus during the process and rna remains in the nucleus.
○ rna leaves the nucleus during the process and dna remains in the nucleus.

Explanation:

To solve this, we analyze each option:

1. DNA does not transform into protein directly; it uses RNA (transcription and translation), so first two options are wrong.
2. DNA stays in the nucleus, and RNA (mRNA) is transcribed in the nucleus and then leaves to the cytoplasm for translation. So the option about RNA leaving nucleus and DNA remaining is correct.

Answer:

D. RNA leaves the nucleus during the process and DNA remains in the nucleus. (Note: Assuming the last option is D, if options were labeled A - D as per typical MCQ, with the last option being the correct one. If original options had different labels, adjust accordingly, but based on content, the correct statement is "RNA leaves the nucleus during the process and DNA remains in the nucleus".)
