Web28 okt. 2024 · During this DNA elimination process ~12,000 internal eliminated sequences (IESs), many of which are related to transposons, are removed from the new MAC. It has been revealed that IESs are targeted for heterochromatin formation followed by DNA elimination by ~29-nt small RNAs, called scnRNAs. WebRNA Polymerase (Pol) binds until the promoter, which positions the catalytic site of who enzyme at the +1 site, where the first base is transcribed into RNA. RNA Pol reads the genen on the template DNA strand by 3’ to 5’ and synthesizes RNA from 5’ go 3’. The general structure are a bacterial gens and its corresponding mRNA are shown below.
