Open vs closed mitosis
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… 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.

WebNational Center for Biotechnology Information WebDuring mitosis the cell nucleus breaks down and two new, fully functional, nuclei are formed. Cytokinesis is the process that divides the cytoplasm into two distinctive cells. Interphase G1 Phase The first stage of interphase is called the G1 phase, or first gap, because little change is visible.
