WebDNA Polymerase reads from the 3’ to 5’ in one strand. In order to make the other strand it adds nucleotides in the 3’ end. For example, if the top strand is from 5’ to 3’, the polymerase simply adds nucleotides to the 3’ end since the strands are anti parallel.

WebRNA polymerase I is located in the nucleolus, a specialized nuclear substructure in which ribosomal RNA (rRNA) is transcribed, processed, and assembled into ribosomes (Table … WebAs it moves farther along the mRNA, this chain grows (Figure 2). Once a ribosome has finished reading a blueprint, it releases a protein into the cell. That ribosome is then ready to repeat the process. Viruses use our ribosomes to make their own proteins The universal use of DNA, mRNA, and amino acids is what make it possible for viruses to exist.
Web"RNA polymerases are enzymes that transcribe DNA into RNA. Using a DNA template, RNA polymerase builds a new RNA molecule through base pairing. For instance, if there is a G in the DNA template, RNA polymerase will add a C to the new, growing RNA strand. RNA polymerase always builds a new RNA strand in the 5’ to 3’ direction." Translation
WebRNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter.
