Let us go over the definitions and the functions of each term:
a) Gene is a bit vague but in general it means a part of DNA that encodes one protein. Genes are the building blocks of our genomes but not the answer to this question.
b)mRNA. This is correct. The name itself means messengerRNA and its role is to copy the genetic information in the nucleus and bring it outside to be translated into protein.
c) ATP is an important molecule in our metabolism; energy is stored in this molecule and then used. It has no relationship to the mechanisms concerning DNA.
d) Thymine is one of the 4 nucleotide bases that are found in DNA, the other three being guanine, cytosine and adenine. They are essential components of a nucleotide (building blocks of DNA and RNA) but again, they do not transfer information out of the nucleus.

Which answer choice does not contain at least one cellular process inhibited by antibiotics?
USPshnik [31]
<span>Antibiotics work by selectively targeting the reproduction or growth of specific bacteria cells and by not attacking human DNA. Antibiotics do not, or should not, target and affect human DNA gyrases, although they should target the specific bacteria growth. The host, (human) DNA needs to remain unharmed while the bacteria does not replicate.</span>
