WebbThe process of mitosis is divided into four stages: prophase, metaphase, anaphase, and telophase. During prophase, the chromatin (loosely packed DNA) condenses into visible chromosomes. The nuclear membrane dissolves, and spindle fibers begin to form from the centrioles located at opposite poles of the cell.

Some cell … WebbProphase I is further divided into sub-stages: Leptotene: In this stage, the initiation of chromosome condensation takes place and it attains a composite form. Zygotene: In this, the homologous chromosomes pairs, the process is called chromosomal synapsis. It is followed by the generation of a composite composition called the synaptonemal complex. WebbProphase of meiosis two sees the chromosomes condense and the nuclear envelope unravel if necessary. The mitotic spindle forms during prophase, and the centrosomes move to the opposite ends of the cell. The mitotic spindle has microtubules that capture the chromosomes.
