If a scientist wanted to prevent a regulatory protein from changing gene expression,he must prevent physical contact between the protein and _____.
A)ribosomes
B)DNA
C)ribozymes
D)mRNA

Question

Quizplus · Accepted Answer

Regulatory proteins function by binding to specific DNA sequences, which results in changes to gene expression. If a scientist wants to prevent this from happening, they must prevent physical contact between the protein and the DNA. The other choices, ribosomes, ribozymes, and mRNA are not involved in the direct regulation of gene expression by regulatory proteins.
