What Causes The Unwinding Of The DNA Double Helix?

WebC. Ligase joins the DNA strand by catalyzing the formation of a phosphodiester bond between the adjacent bases. D. Topoisomerase helps in relieving the tension created during the unwinding of DNA. Hence, the enzyme that catalyzes the separation of DNA strands during DNA replication is Helicase. So, the correct answer is 'Helicase'. WebDNA helicase. is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and … literacy lead cover letter https://wylieboatrentals.com

WebDeoxyribonucleic acid (DNA) be a chemical that in the biological instructions that induce each species single. WebCertain proteins bind to the origin of replication while an enzyme called helicase unwinds and opens up the DNA helix. As the DNA opens up, Y-shaped structures called replication forks are formed (Figure 9.10). Two replication forks are formed at the origin of replication, and these get extended in both directions as replication proceeds.
