WebThe first step of DNA replication is the unwinding parent double helix molecule so that each strand acts as a template for the new strand. Unwinding mechanism is very complex. Hydrogen bonds between two strands are broken. This is achieved by enzymes called DNA helicases which move along DNA and separate the strands. WebMar 31, 2024 · In the S phase (synthesis phase), DNA replication results in the formation of two identical copies of each chromosome— sister chromatids —that are firmly attached at the centromere region,as shown in Figure 24.1. 26. At this stage, each chromosome is made of two sister chromatids and is a duplicated chromosome.
