Question

Which of the following helps transfer of genetic information from nucleus to cytoplasm?

• A. DNA
• B. RNA
• C. Lysosome
• D. All of the above

Answer 1

The correct option is B RNA

Transfer of genetic information from the nucleus to the cytoplasm happens by the process of transcription and translation. Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. The translation is the final step on the way from DNA to protein. It is the synthesis of proteins directed by an mRNA template. Thus, the genetic information in DNA present in the nucleus finally reaches the cytoplasm in the form of proteins. In this process, RNA is the molecule that helps in the transfer of information from the nucleus to the cytoplasm.
Hence, the correct answer is (B).
