WebJul 7, 2024 · G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase. The cell synthesizes proteins and continues to increase in size. The G2 phase is the second gap phase. In the latter part of interphase, the cell still has nucleoli present. WebJan 22, 2024 · Diploid cells reproduce through mitosis. In mitosis, a cell makes an identical copy of itself. It replicates its DNA and distributes it equally between two daughter cells that each receive a full set of DNA. Somatic cells go through mitosis and (haploid) gametes undergo meiosis. Mitosis is not exclusive to diploid cells. Diploid Life Cycles
