Detailed explanation-1: -G1 is followed by S phase (synthesis), during which DNA replication takes place. The completion of DNA synthesis is followed by the G2 phase (gap 2), during which cell growth continues and proteins are synthesized in preparation for mitosis.
Detailed explanation-2: -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.
Detailed explanation-3: -Explanation: DNA replication involves the separation of the two original DNA strands. Both of these strands are then replicated using DNA polymerase. This results in two DNA double helices, each with a new strand and an original strand.
Detailed explanation-4: -Note:Replication of DNA molecule (duplication of DNA) occurs during S phase of Interphase. In this way, the genetic material of a cell is doubled before it enters the division phase, where division of genetic material takes place.
Detailed explanation-5: -This continuously synthesized strand is called the leading strand. The other new strand, which runs 5’ to 3’ away from the fork, is trickier. This strand is made in fragments because, as the fork moves forward, the DNA polymerase (which is moving away from the fork) must come off and reattach on the newly exposed DNA.
