Emergency treatment for stroke depends on whether you're having an ischemic stroke blocking an artery â the most common kind â or a hemorrhagic stroke that involves bleeding into the brain.
Top 10 unbelievable historical concurrencies. Transcriptional regulation is a term used to describe a number of biological processes by which transcription, the process through which the genetic data stored in DNA is transcribed to RNA, is controlled.egulation of gene expression can occur at every level of the central dogma of biology. Transcriptional regulation is a specific form of gene regulation that occurs during the transcription process by moderating the rate of transcription.
If lactose and glucose are present, the cell will use all of the glucose before the lac operon is turned on. This type of control is termed catabolite repression. To prevent lactose metabolism, a second level of control of gene expression exists. The promoter of the lac operon has two binding sites. One site is the location where RNA polymerase binds. The second location is the binding site for a complex between the catabolite activator protein (CAP) and cyclic AMP (cAMP). The binding of the CAP-cAMP complex to the promoter site is required for transcription of the lac operon.
