Mitosis - Explanation, Features, Satges, Functions and Significance

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… WebbSpermatocyte. Spermatogenesis as the cells progress from spermatogium, to primary spermatocytes, to secondary spermatocytes, to spermatids and to Sperm. Spermatocytes are a type of male gametocyte in animals.

WebbThe characteristic features of the Prophase stage are as follows: From the prophase diagram, it can be seen that the compact mitotic chromosomes during prophase. Chromosome condensation occurs during the prophase. Two chromatids attached at the centromere can be seen in the prophase diagram in the chromosomes. WebbProphase The first half of prophase sees the cell prepare for division by setting up certain organelles and structures. The chromosomes within the nucleus begin to condense. The chromosomes are usually long and string-like, but by coiling up they can be more easily moved around the cell. Webb1. Prophase features: Chromosomes condense themselves and become visible; Each chromosome is composed of two sister chromatids; Spindle fibers erupt from centromeres; Nuclear membrane disappears; 2. Metaphase features: Chromosomes line up at the plate of metaphase; Centrioles with spindle fibers are at opposite ends of the cell roanoke virginia speed cameras
