Phases Of The Mitosis
Mitosis is a type of cell division in which one cell is divided to produce two new cells that are genetically identical.

-
Cell Cycle
G1 Phase
the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps
S Phase
the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.
G2 Phase
the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.
-
Prohase
Chromosomes become even more condesed,making them compact.
-
-
Metaphase
-
All this stage, the two kinetochores on each chromosome must bind to microtubules at opposite poles of the spindle.
Anaphase
-
-
Microtubules not attached to the chromosomes elongate and push to separate the poles and make the cell longer.
Telophase
-
The new nuclei are formed, one for each set of chromosomes
-
-
Cytokinesis
Performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell.
Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.
The contractile ring shrinks to the point that there are two separate cells each bound by its own plasma membrane.
Spindle Anatomy
The spindle is the structure that pulls the chromatids to opposite ends of the cell during the cell division processes of mitosis.
-
Chromosomes
Each chromosome has two chromatids, and each chromatid has a kinetochore.
Centromere
, structure in a chromosome that holds together the two chromatids.
