What is transcriptional regulation?

Transcription regulation is a term used to describe a number of biological processes to control transcription, a process by which genetic data stored in DNA is rewritten to RNA. Transcription is one of the main steps in the central dogma biology, which describes the overall process by which the genes are expressed. Uncooked genetic data is contained in double cut DNA, but is mixed with a large amount of irrelevant data. Through the transcription, the data contained in the two -grain DNA is rewritten to the single -fold RNA molecule and the irrelevant data is connected. The final main step is translated when RNA transcriptions are used to produce proteins, the final units of gene expression, which serve countless functions in any organism.

Gene expression control can occur at each level of central dogma biology. Transcription regulation is a specific form of gene regulation that occurs during transcriptioncerocery by moderating transcription speed.Sometimes this involves stopping transcription solely to stop the expression of a particular gene, while at other times this may mean activation of transcription to activate genes that are used only during certain environmental conditions. Transcription regulation is effective because it is the first main step of gene expression. It requires significantly less use of biological sources than regulation by preventing translation or regulation that affects the performance of already translated proteins.

Transcription regulation is incredibly important to maintain the health of the body and involves many different factors. For example, there is a time factor for transcription regulation; To maintain various important biological functions, it is often important that proteins are produced at a specific rate. Likewise, the area on environmental factors may require transcription to start quickly. It is also important to ensure that there is a transcript inappropriate extent; If too much or too few proteins are produced, important balance in the body may be adversely affected.

There are many different transcriptional regulation mechanisms. For example, repressors and enhancers are specialized molecules that either inhibit or increase the ability of the protein to bind to the promoter to the DNA to start transcription. The placement of RNA polymerase, a protein that is RNA synthesis, is necessary transcription factors, at a suitable location on the DNA chain to initiate transcription. A higher concentration of a given transcription factor could then lead to a higher level of transcription.
