Detailed explanation-1: -DNA replication involves unwinding two strands of parent DNA, copying each strand to synthesize complementary strands, and releasing the parent and daughter DNA.
Detailed explanation-2: -DNA unwinds at the origin of replication. New bases are added to the complementary parental strands. One new strand is made continuously, while the other strand is made in pieces. Primers are removed, new DNA nucleotides are put in place of the primers and the backbone is sealed by DNA ligase.
Detailed explanation-3: -The correct answer is (D) RNA primase makes the RNA primer, while DNA Pol epsilon extends that primer with DNA. DNA polymerase epsilon is the enzyme that synthesizes new strands of DNA during replication.
Detailed explanation-4: -DNA replication occurs through the help of several enzymes. These enzymes “unzip” DNA molecules by breaking the hydrogen bonds that hold the two strands together. Each strand then serves as a template for a new complementary strand to be created. Complementary bases attach to one another (A-T and C-G).
