Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. Step 2: Primer Binding. The leading strand is the simplest to replicate. Step 3: Elongation. Step 4: Termination. WebFor example, when a temperate bacteriophage infects a bacterial cell, it replicates by means of a lysogenic cycle (Figure 3), and the viral genome is incorporated into the genome of the host cell.
