In animal cells, two pairs of centrioles formed from the replication of one pair are located outside of the nucleus.Īt the end of interphase, the cell enters the next phase of meiosis: Prophase I.The nucleus is bounded by a nuclear envelope and the cell's chromosomes have duplicated but are in the form of chromatin.Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA. In the latter part of interphase, the cell still has nucleoli present. In G2, after DNA replication in S phase, as cell enter mitotic prophase. Meiosis II is generally regarded as being very similar to mitosis, except for the presence of two parent cells, instead of only one.
Note that the G in G2 represents gap and the 2 represents second, so the G2 phase is the second gap phase. The cell synthesizes proteins and continues to increase in size. G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase.In most cells, there is a narrow window of time during which DNA is synthesized. S phase: The period during which DNA is synthesized.Note that the G in G1 represents gap and the 1 represents first, so the G1 phase is the first gap phase. In this phase, the cell increases in mass in preparation for cell division. Prophase 1 and 2 are two phases in the meiotic division of cells which produce gametes in order to carry out their sexual reproduction. G1 phase: The period prior to the synthesis of DNA.
At the end of the meiotic process, four daughter cells are produced. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. Overall, meiosis II resembles the mitotic division of a haploid cell. The two cells produced in meiosis I go through the events of meiosis II in synchrony. There are two stages or phases of meiosis: meiosis I and meiosis II. In meiosis II, the connected sister chromatids remaining in the haploid cells from meiosis I will be split to form four haploid cells.
