Genetic information is transmitted from DNA to
Alexus [3.1K]


The best answer is D.

Genetic information for synthesis of a protein is transmitted from DNA to the ribosomes, which are the site for protein synthesis. This is facilitated by messenger RNA or mRNA in short.

In the nucleus of the cell, information from DNA is copied (transcribed) onto mRNA which leaves the nucleus and enters the cytoplasm where it attaches to the ribosome. The information on the attached  mRNA is  decoded and read ( translated) by transfer RNA (tRNA) which then brings corresponding amino acids to the ribosome to be linked together to form the protein.

Why does transcription occur in the nucleus and not in the cytoplasm in eukaryotes?
pav-90 [236]
Transcription is the process by which the DNA molecule makes an RNA molecule using enzyme RNA polymerase and other proteins. The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus.
