WebWhat are the 3 types of gene regulation in bacterial cells? At what location in the "central dogma" schematic do they act on? transcriptional between DNA and mRNA, translational between mRNA and protein, and post translational between protein and activated protein. WebAfter RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point on the template strand. 2) Elongation. The polymerase moves downstream, unwinding the DNA and elongating the RNA transcripts 5' --> 3'. In the wake of transcription, the DNA strands re-form a double helix.
WebThe flow of genetic information in cells from DNA to mRNA to protein is described by the Central Dogma of molecular biology (Figure 16.2). When a cell needs a particular protein, the gene that codes for that protein is activated and a single-stranded mRNA copy is made of the gene, in a process called tr a nscription .
