Which of the following is true concerning gene expression:

Question

Quizplus · Accepted Answer

The regulation of gene expression can occur at many levels, including transcriptional initiation, post-transcriptional processing, translation, and protein degradation. Therefore, option D is the correct answer. Option A is incorrect because an increase in expression can also result from increased stability of mRNA or increased efficiency of translation. Option B is incorrect because mRNA levels can also be affected by mRNA stability and processing. Option C is incorrect because attenuation is a mechanism used in prokaryotic cells and not in eukaryotic cells. Option E is incorrect because gene copy number can affect the level of gene expression.
