Helicase biology

WebHelicase breaks the hydrogen bonds between strands of DNA, unwinding the double helix. The unwinding action causes the strand to become more tightly wound further up from the fork. Topoisomerase periodically breaks the peptide backbone of one strand to relieve some of that tension created by helicases. edit:wording. GhostofJeffGoldblum.

De helicasen zijn een groep van enzymen die de dubbele DNA-spiraal ontwinden en door het verbreken van de waterstofbruggen de twee strengen uit elkaar laten gaan, waardoor andere enzymen zoals RNA-polymerase een stukje van de enkelvoudige streng kunnen aflezen (transcriptie). Helicase zorgt er dus voor dat het dubbelstrengs-DNA uit elkaar 'ritst'. Helicase is voor alle levende weze… netgear wnda3100 drivers for windows 7 https://glynnisbaby.com
