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.
A transcription factor (blue) binds to DNA (red) and alters which genes are turned on, or expressed. Image courtesy of David S. Goodsell, RCSB Protein Data Bank. Transcription factors are proteins that control which genes are turned on or off in the genome.They do so by binding to DNA and other proteins.Once bound to DNA, these proteins can promote or block the enzyme that controls the reading, or âtranscription,â of genes, making genes more or less active.Transcription factors are essential for the regulation of genes.hrough the action of transcription factors, the various cells of the body, which all have the same genome, can function differently. These proteins are so important to life that they are found in all living organisms. Roughly 8% of genes in the human genome encode transcription factors.
