In eukaryote cells, which travels out of the nucleus to a ribosome?

• A. RNA
• B. DNA
• C. Both DNA and RNA
• D. Neither

Answer: (A)

In eukaryotes, genetic information moves from DNA in the nucleus to RNA, which then travels out of the nucleus into the cytoplasm where ribosomes are located to synthesize proteins. The messenger RNA carries the coded instructions from the DNA and serves as the template that the ribosome reads to assemble the corresponding amino acids. DNA stays inside the nucleus and isn’t exported, so it cannot travel to the ribosome. Ribosomal RNA is involved in forming the ribosome itself, but the message that leaves the nucleus to be translated is RNA.
