Explanation:
Detailed explanation-1: -Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Detailed explanation-2: -Synthetic phase or S-phase of interphase, is the stage of cell cycle where DNA synthesis or replication takes place.
Detailed explanation-3: -The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.
