WebbMeiosis is a form of nuclear division that results in the production of haploid cells from diploid cells. It produces gametes in plants and animals that are used in sexual … Webb14 juli 2015 · It is metabolic stage between telophase of meiosis I and prophase of meiosis II. Chromosome are elongated but chromatin reticulum is not formed. Protein and RNA synthesis may occur. Centrosome or centriole pairs undergo replication in animal cells. However, there is no DNA synthesis.

During prophase, chromatin condenses into chromosomes , and the nuclear envelope (the membrane surrounding the nucleus) breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles of the cell. Centrioles are small organelles found only in eukaryotic cells.
WebbAnimal cells undergo “open” mitosis, where the nuclear envelope breaks down before the chromosomes separate, whereas fungi undergo “closed” mitosis, where chromosomes divide within an intact cell nucleus.

Webb24 feb. 2012 · Prophase The first and longest phase of mitosis is prophase ( Figure below ). During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the b…
