WebTranscription is something we do in our everyday lives, and it's also something our cells must do, in a more specialized and narrowly defined way. In biology, transcription is the … WebA promoter is a sequence of DNA needed to turn a gene on or off. The process of transcription is initiated at the promoter. Usually found near the beginning of a gene, the promoter has a binding site for the enzyme used to make a messenger RNA (mRNA) molecule. What is promoter and its function?

WebEach gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription. Elongation. One strand of DNA, the template strand, acts as a template for RNA polymerase. WebMar 1, 2024 · The two main steps in gene expression are transcription and translation. Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.
In genetics, a promoter is a sequence of DNA to which proteins bind to initiate transcription of a single RNA transcript from the DNA downstream of the promoter. The RNA transcript may encode a protein (mRNA), or can have a function in and of itself, such as tRNA or rRNA. Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5' region o… Webpromoter. (prə-mō′tər) n. 1.
