Detailed explanation-1: -Once the DNA is unzipped it forms a template for the binding of the DNA Polymerase and other accessory proteins. The synthesis of a new strand occurs using this unzipped DNA as the template in the 5’-3’ direction.

Detailed explanation-2: -NTP’s are used in the synthesis of RNA primers and ATP is used as an energy source for some of the enzymes needed to initiate and sustain DNA synthesis at the replication fork. The nucleotide that is to be incorporated into the growing DNA chain is selected by base pairing with the template strand of the DNA.

Detailed explanation-3: -Once the DNA strands have been unwound, they must be held apart to expose the bases so that new nucleotide partners can hydrogen-bond to them. The enzyme DNA polymerase then moves along the exposed DNA strand, joining newly arrived nucleotides into a new DNA strand that is complementary to the template.

Detailed explanation-4: -DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.
