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)Lipids are soluble in the nuclear membrane and serve to transfer information from the DNA to the cytoplasm,where protein synthesis takes place.

Question

Quizplus · Accepted Answer

Messenger RNA (mRNA) is transcribed from DNA in the nucleus and carries the genetic information to the ribosomes in the cytoplasm, where it serves as a template for protein synthesis. This process is called transcription and translation. Option A is incorrect because DNA replication is not directly involved in protein synthesis. Option C is incorrect because proteins are the end products of protein synthesis, not the mechanism of information transfer. Option D is not correct as lipids are not involved in the transfer of genetic information.
