transcription Stages of Transcription The process of DNA transcription can be split into 3 main stages: initiation, elongation & termination These steps are also involved

transcription Initiation is the beginning of transcription It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter This signals the DNA to In eukaryotes, transcription and modification of mRNA happens exclusively in the nucleus After mRNA processing, the mature mRNA travels out of the nucleus
