Which Level of Gene Regulation Controls the Expression of Heat

Question

Which level of gene regulation controls the expression of heat shock proteins?
A) Transcription
B) Post-transcription processing
C) Translation
D) Post-transcription processing and translation
E) All of these are correct.

Accepted Answer

The expression of heat shock proteins is primarily regulated at the transcriptional level, through the activation of transcription factors that bind to the promoter region of the heat shock protein genes. While there may be some post-transcriptional and translational control, such as mRNA stability or protein degradation, these are secondary mechanisms that act downstream of transcriptional regulation.
