I would say B.(RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.)
RNA is a single strand and can leave the nucleus easily but the DNA is double strands that are twisted together and are big and cannot leave the cell
Answer:
B
Explanation:
Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.
Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.
