Mitosis
STAGE BY STAGE OVERVIEW
What is mitosis
and how does they work?
Mitosis is a process by which a cell divides to produce two genetically identical daughter cells each with the same number of chromosomes as the parent cell
What is mitosis?
MITOSIS WORKS BY CAREFULLY DIVIDING THE CELL’S
NUCLEUS AND GENETIC MATERIAL SO THAT EACH NEW
CELL GETS AN IDENTICAL SET OF CHROMOSOMES. THE
DNA FIRST CONDENSES INTO CHROMOSOMES, LINES UP
IN THE CENTER, SEPARATES INTO TWO SETS, AND FINALLY
THE CELL SPLITS INTO TWO IDENTICAL DAUGHTER CELLS.
How does they work!
S tages of mitosis
- Eukaryotic cell division replicatory . mitosis is the process by which a cell replicates it's chromosomes and men segregates them producing two nuclei in preparation of cytokinesis
-cytokinesis follow mitosis by equal division of the cell content cells that have identical genome
Prophase
Chromosomes condense and become visible. The nuclear membrane dissolves, and spindle fibers start forming.
Metaphase
Chromosomes align at the equator of the cell.
Spindle fibers attach to the centromeres.
Anaphase
Sister chromatids are pulled apart by spindle
fibers toward opposite poles.
Telophase
Nuclear membranes reform around each set of chromosomes. Chromosomes begin to uncoil back into chromatin.
Cytokinesis The cytoplasm divides, forming two genetically identical daughter cells.
Two new cells are formed. Each cell has the same number of chromosomes as the original parent cell They are genetically identical
