Summary of Transcription
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA, particularly mRNA, by the enzyme RNA polymerase. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript. The major steps of transcription include initiation, elongation, and termination.
Flashcards on Transcription
Transcription factors bind to a unique DNA sequence termed the , which signals to initiate DNA transcription.
