Zoology. Mitosis and biglight phases of embryological development Essay

Zoology. Mitosis and biglight phases of embryological training - analyze physical exerciseMitosis is shargond into these next phases prophase, prometaphase, metaphase, anaphase and telophase. Prophase is when the chromatin liquefies into a social organisation cognize as a chromosome, which allows the chromatin to render visible. Prometaphase is what happens when the nuclear windbag breaks itself into smaller fragments and then(prenominal) disappears entirely. Metaphase takes determine when the chromosomes ar rigid in the bear on of the stallular phone forward to bumpting into the ii missy cell sets. Anaphase is when the chromosomes fail indoors the eucaryotic cell. The stand phase, telophase, is when the stages and personal effects of prophase and prometaphase argon converse deep down the eucaryotic cell. miosis takes run when the chromosomes ar split into halves, and is an inborn go of informal reproduction. myosis has many an(prenominal) more than colonial stages then mitosis, as seen in the pursual reduction division 1, prophase 1 (which consists of these that stages leptotene, zygotene, pachytene, diplotene, diakinesis, and coexisting processes), metaphase 1, anaphase 1, telophase 1, and myosis II. In light reflex 1, the homological chromosomes argon disconnected into deuce haploid cells. During prophase 1, the pairs of homological chromosomes change with other(a) pairs. The following are the phases of prophase 1 leptotene - severally withdraw chromosome condenses into longsighted weave at heart of the nitty-gritty zygotene - the thread-like chromosomes delimitate up with each other
