Question

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 transcribed to mRNA and transported to the cytoplasm, where mRNA serves as an information carrier for protein synthesis.B.Transfer RNA takes information from DNA directly to a ribosome, where protein synthesis takes place.C.Proteins transfer information from the nucleus to the ribosome, where protein synthesis takes place.D.Messenger RNA is transcribed from a protein and transfers information from the nucleic acids in the cytoplam to the nucleus where protein synthesis takes place.

Answer 1

Answer:

The answer is A.

Explanation:

From DNA inside the nucleus , the messenger RNAs is synthesized and the mRNA is given to cytoplasm. This mRNA will lead to ribosome which protein synthesis occurs. Due to sequence in mRNA, the tRNA collect the needed aminoacid and synthesize the protein by collecting amino acid from cytoplasm due to codons in mRNA.
