During Which Phase of Interphase Is Dna Replication?

S phase is the period during which DNA replication occurs.

Does DNA replication occur in G1 phase?

G1 is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. ... Before a cell begins DNA replication, it must ensure that it is biologically ready to take on such a process. G1 is the phase when this cellular monitoring takes place.

What happens during the G2 stage of interphase?

G2 Phase. During the G2 phase, the cell prepares to enter mitosis. The DNA has already been duplicated during the S phase, so the G2 phase is when the organelles of the cell need to duplicate. Not only will the duplicated DNA be evenly divided during cell division, but so will the organelles.
