Bacterial and eukaryotic cells primarily control gene expression at the level of transcription. If instead cells exerted control of gene expression primarily at the post-translational level, what would be different?
A) The ability to rapidly respond to environmental change would be reduced.
B) Cells would expend significantly more energy.
C) Genes would no longer be transcribed.
D) Translation of mRNA into protein would not occur.

Controlling gene expression at the post-translational level means that the cell would first transcribe and translate proteins before regulating their activity or stability. This process is more energy-intensive because it involves synthesizing proteins that may not be needed immediately or in large quantities, leading to wasted resources.
