The centrosomes that were duplicated during interkinesis move away from each other toward opposite poles, and new spindles are formed. If nuclear envelopes were formed, they fragment into vesicles. 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. Prophase II If the chromosomes decondensed in telophase I, they condense again.The nucleus is bounded by a nuclear envelope and the cell's chromosomes have duplicated but are in the form of chromatin.

In the latter part of interphase, the cell still has nucleoli present.

You can remember the order of the phases with the famous mnemonic: P lease P ee on the MAT. Note that the G in G2 represents gap and the 2 represents second, so the G2 phase is the second gap phase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. The cell synthesizes proteins and continues to increase in size. Prophase II: chromosomes condense, nuclear envelope disintegrates and spindle fibres. The mitotic prophase and prophase II are quite comparable. Cytokinesis results in the formation of two daughter cells. It explains how mitosis and meiosis vary from one another. With the pairing of homologous chromosomes and the exchange of genetic material, prophase I is highly complicated.

G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase. The prophase, which occurs in two phases, prophase I and prophase II, is what makes the process lengthier.

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. An additional step called crossing over occurs during prophase I of meiosis.

G1 phase: The period prior to the synthesis of DNA. Prophase: Definition, Checkpoints, Diagram, and Examples.

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.

There are two stages or phases of meiosis: meiosis I and meiosis II.
