Detailed explanation-1: -During the G1 phase, the cell grows in size and synthesizes the cellular contents. Cells in the G1 phase do not divide, rather make preparations to divide. DNA replicates in S phase and overall cell growth is observed in G2 phase.
Detailed explanation-2: -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. During this time, the cell grows in preparation for DNA replication, and certain intracellular components, such as the centrosomes undergo replication.
Detailed explanation-3: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell.
