WebDuring interphase, DNA is synthesized. Interphase is a preliminary phase that is separated into three parts: Gap1 (G1), Synthesis (S), and Gap2 (G2). True cell division occurs during the M phase of mitosis. S phase : The replication phase is known as the S phase. DNA replication consumes the majority of the cell's resources.

In fact, the chromosomes become so dense that they...

WebReplication occurs before cell division, during the S phase of the cell cycle. However, replication only concerns the production of new DNA strands, not of new cells. Some people think that in the leading strand, DNA is synthesized in the 5’ to 3’ direction, while in lagging strand, DNA is synthesized in the 3’ to 5’ direction.
