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.

Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. WebNormally, transcription begins when an RNA polymerase binds to a so-called promoter sequence on the DNA molecule. This sequence is almost always located just upstream from the starting point for... polyester wire
