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) Lipids are soluble in the nuclear membrane and serve to transfer information from the DNA to the cytoplasm, where protein synthesis takes place.
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) DNA from a single gene is replicated and transferred to the cytoplasm, where it serves as a template for protein synthesis.

Messenger RNA (mRNA) is transcribed from a single gene in the nucleus and serves as a template for protein synthesis in the cytoplasm. The mRNA is transported out of the nucleus and into the cytoplasm, where it is read by ribosomes and used to synthesize proteins. Lipids and proteins are important components of cell membranes but are not involved in the mechanism of information transfer from DNA to protein synthesis. DNA replication occurs prior to cell division and is not involved in the transfer of information for protein synthesis.
