Once researchers identified DNA as the unit of inheritance,they asked how information was transferred from the DNA in the nucleus to the site of protein synthesis in the cytoplasm.What is the mechanism of information transfer?
A)DNA from a single gene is replicated and transferred to the cytoplasm,where it serves as a template for protein synthesis.
B)Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm,where protein synthesis takes place.
C)Proteins transfer information from the nucleus to the ribosome,where protein synthesis takes place.
D)Transfer RNA takes information from DNA directly to a ribosome,where protein synthesis takes place.

Messenger RNA (mRNA) is transcribed from DNA in the nucleus, and then migrates to the ribosomes in the cytoplasm where it serves as a template for protein synthesis. This process is called transcription and translation. Therefore, option B is the correct answer.
