How does gene transcription work
WebIf a gene does get transcribed, it is likely going to be used to make a protein (i.e. expressed). In general (but not always) the more often a gene is transcribed, the more protein that will be made. ... Other transcription factors repress transcription. This repression can work in a variety of ways. As one example, a repressor may get in the ... WebTranscription is the process of copying a segment of DNA into RNA. The segments of DNA transcribed into RNA molecules that can encode proteins are said to produce messenger RNA (mRNA). Other segments of DNA are …

WebKey points: Transcription factors are proteins that help turn specific genes "on" or "off" by binding to nearby DNA. Transcription factors that are activators boost a gene's … WebWhen a gene is subject to positive transcriptional control, the binding of a specific transcription factor to the regulatory element promotes transcription. When a gene is subject to negative transcriptional control, the binding of a specific transcription factor to a regulatory element s represses transcription.
WebIn other words, there is a one-to-one correspondence of bases between the gene and the mRNA transcribed from the gene (excepting 5′ and 3′ noncoding regions). WebTranscription Factors. Transcription factors are proteins possessing domains that bind to the DNA of promoter or enhancer regions of specific genes. They also possess a domain that interacts with RNA polymerase II or other transcription factors and consequently regulates the amount of messenger RNA (mRNA) produced by the gene.
