Detailed explanation-1: -Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. As a result of semi-conservative replication, the new helix will be composed of an original DNA strand as well as a newly synthesized strand.

Detailed explanation-2: -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-3: -The very first step in DNA replication is unzipping the double helix of the DNA molecule, the unwinding of DNA occurs by enzyme helicase and gyrase. After unwinding the DNA forms a replication fork and both the strands act as a template for the formation of new strands.
