Question

all but one of the following are involved in the transfer of a genetic message from the nucleus to the ribosome. that is
a $\ce{co_{2}}$
b dna
c mrna
d trna

Explanation:

The question asks for the molecule not involved in transferring genetic messages from the nucleus to ribosomes. DNA stores genetic info in the nucleus; mRNA transcribes DNA’s message and moves to ribosomes. CO₂ is a metabolic waste product unrelated to genetic message transfer. (Note: Option D is partially obscured but CO₂ is clearly unrelated.)

Answer:

A. CO₂
