WebDNA replication is an important process that occurs during cell division. It is also known as semi-conservative replication, during which DNA makes a copy of itself. DNA replication takes place in three stages: Step 1: Initiation The replication of DNA begins at a point known as the origin of replication. WebThe DNA double helix is held together by base stacking interactions and hydrogen bonds. If each strand is to be read and copied individually, there must be some mechanism responsible for helping to dissociate the two strands from one another. Energetically, this is an endergonic process.
