The fresh “RNA factory” design to have eucaryotic RNA polymerase II. Besides really does the newest polymerase transcribe DNA to the RNA, but it also deal pre-mRNA-control protein for the their tail, which can be after https://datingranking.net/it/valuta-il-mio-appuntamento/ that moved to the brand new nascent RNA at the compatible (even more. )

The moment RNA polymerase II has generated on 25 nucleotides of RNA, the five? prevent of your own this new RNA molecule is actually altered because of the introduction of a “cap” you to definitely include an altered guanine nucleotide (come across Contour six-22B). The capping response is done because of the around three enzymes pretending inside the succession: one (a phosphatase) removes that phosphate regarding 5? המשך…
