WebEukaryotic Cell WebMitosis (the M phase) The process of mitosis, or cell division, is also known as the M phase. This is where the cell divides its previously-copied DNA and cytoplasm to make two new, identical daughter cells. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Stages of mitosis Cancer and cell cycle regulation

WebThe mechanism of local nuclear envelope breakdown in a closed mitosis therefore closely mirrors nuclear envelope breakdown in open mitosis 3, revealing an unexpectedly high … The primary result of mitosis and cytokinesis is the transfer of a parent cell's genome into two daughter cells. The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of eac…
