Question

Quizplus · Accepted Answer

Gene expression is primarily regulated at the level of transcription in both eukaryotes and prokaryotes. This is because transcription is the step in which DNA is transcribed into RNA, serving as the precursor for proteins. Controlling the rate and specificity of transcription allows cells to regulate the amount and types of proteins produced, which is key to their ability to respond to diverse stimuli and maintain homeostasis. While other levels of regulation (e.g. translation, mRNA stability, protein stability) can also be important, the level of transcription is considered the primary point of control.
