A chemical that causes the formation of covalent bonds between adenines and thymines on opposite DNA strands is added to a cell in such a way that the bonds between the nucleotides cannot be broken.How does this drug affect gene expression in the cell?
A) The chemical increases the efficiency of protein production by making it easier for tRNA to interact with the correct mRNA codons.
B) The chemical prevents transcription from occurring so that proteins cannot be made.
C) The chemical prevents protein production because once made, the RNA cannot separate from its DNA template.
D) The chemical has no effect on protein production because mRNA contains uracil rather than thymine.
