WebJun 14, 2024 · An enzyme called helicase then separates the DNA strands by breaking the hydrogen bonds between the nitrogenous base pairs. Recall that AT sequences have fewer hydrogen bonds and, hence, have weaker interactions than guanine-cytosine (GC) sequences. These enzymes require ATP hydrolysis. WebReplication begins at special sites along the DNA moleculecalled Origins of replication. It is at these sites that the helix opens and moves away from. This movement produces the replication Here the new strands of DNA are added. In order for the DNA strands to separate,3 types of enzymes are needed. Helicases, single-strand bindingproteinsand WebThe antiparallel strands of the parent DNA create some problems for DNA polymerase. One quirk of DNA polymerase is that it’s a one-way enzyme — it can only make new strands of DNA by lining up the nucleotides a certain way. But DNA polymerase needs to use the parent DNA strands as a pattern, and they’re going in opposite directions. elite dangerous find pharmaceutical isolators
