Zoology. Mitosis and biglight phases of embryological development - Essay ExampleMitosis is sh bed into these following phases prophase, prometaphase, metaphase, anaphase and telophase. Prophase is when the chromatin liquefies into a structure known as a chromosome, which allows the chromatin to become visible. Prometaphase is what happens when the thermonuclear envelope breaks itself into smaller fragments and then disappears entirely. Metaphase takes place when the chromosomes are situated in the center of the cell former to splitting into the two daughter cell sets. Anaphase is when the chromosomes separate within the eukaryotic cell. The last phase, telophase, is when the stages and effects of prophase and prometaphase are reversed within the eukaryotic cell.Meiosis takes place when the chromosomes are split into halves, and is an essential part of cozy reproduction. Meiosis has many more complex stages then mitosis, as seen in the following meiosis 1, prophase 1 (which consi sts of these further stages leptotene, zygotene, pachytene, diplotene, diakinesis, and synchronous processes), metaphase 1, anaphase 1, telophase 1, and meiosis II. In meiosis 1, the homologous chromosomes are separated into two haploid cells. During prophase 1, the pairs of homologous chromosomes recombine with other pairs. The following are the phases of prophase 1 leptotene - each separate chromosome condenses into long wind inside of the nucleus zygotene - the thread-like chromosomes line up with each other
