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 in eukaryotes?
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 a gene in the nucleus and carries the genetic information from DNA to the ribosome in the cytoplasm, where it is translated into a specific protein. This process is referred to as transcription and translation, respectively. DNA replication does not transfer information directly to the cytoplasm. Proteins and transfer RNA (tRNA) do have roles in protein synthesis but do not transfer information from the nucleus to the ribosome.
