WebOct 23, 2024 · A promoter is a sequence of DNA that helps to control where and when a gene is transcribed. The promoter is located at the 5′ end of the gene and helps to recruit the RNA polymerase enzyme to the gene. The promoter also helps to determine how much RNA is produced from the gene. The role of gene regulators in gene expression is critical. WebA promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA …
