Altering patterns of gene expression in prokaryotes would most likely serve an organism's survival by ________.
A) organizing gene expression, so that genes are expressed in a given order
B) allowing each gene to be expressed an equal number of times
C) allowing an organism to adjust to changes in environmental conditions
D) allowing environmental changes to alter a prokaryote's genome

Question

Quizplus · Accepted Answer

Altering patterns of gene expression in prokaryotes would allow an organism to adjust to changes in environmental conditions, which would increase its chance of survival. This would enable the organism to produce proteins or enzymes that it needs in response to changes in its environment. A and B are incorrect because organizing gene expression or expressing each gene equally does not necessarily affect an organism's survival. D is incorrect because environmental changes cannot alter a prokaryote's genome directly; rather, they can affect gene expression.
