In biology, Mitosis is the process of chromosome segregation and nuclear division that follows replication of the genetic material in eukaryotic cells. This process assures that each daughter nucleus receives a complete copy of the organism's genetic material.
Cell division is the process by which cells replicate in order to replace cell loss, repair tissue damage and reproduce the organism. Two types of cell division are encountered in the Eukaryotic cell viz. Mitotic and Meiotic divisions.
Mitosis 0 hours G0 phase 1. All cells originate from the single source: the fertilized oocyte. 2. All cells except for male and female sex cells (sperms and oocytes) are produced by the process of cell division called mitosis. Fundamental feature of mitosis: both descendant cells contain the same genetic material (DNA) as the parent cell.
Mitosis is the process of cell division in which the daughter cells receive identical copies of DNA, which are also identical to that of the mother cell. Meiosis is the process of cell division that results in the formation of cells containing half the amount of DNA contained in the parent cell, and having different copies of DNA from one another.
Mitosis - nuclear/chemical events resulting in two daughter nuclei which have identical genetic material to each other and to the mother cell. *(Michael) I. Prophase - the first stage of mitosis. The chromosomes condense and become visible . The centrioles form and move toward opposite ends of the cell ("the poles") .
In this lecture we review mitosis, the process by which the chromosomes of somatic cells are apportioned equally to two daughter cells during division. Mitosis ensures that all of our cells inherit the same genetic information. We will compare mitosis with meiosis, which is the process by which the gametes are made.
