Refer to the figure showing the potential points for the regulation of gene expression.  Blocking which point would be considered transcriptional control?

Quizplus · Accepted Answer

Transcriptional control refers to the regulation of gene expression at the level of transcription, i.e., the process of synthesizing RNA from DNA. In the given figure, blocking point 2, which refers to the binding of transcription factors to the promoter region of the gene, would be considered transcriptional control. This is because transcription factors play a crucial role in the initiation of transcription and can either enhance or inhibit the binding of RNA polymerase to the promoter region, thereby regulating gene expression. The other points in the figure represent post-transcriptional and post-translational control.
