what is Interphase and M phase
Before Mitosis the cells have to go through the cell cycle which is divided into two phases, interphase where the cell prepares by doubling its chromosomes and M phase where the division actually occurs. this division process is known as mitosis
1 of 7
describe what happens in prophase
The Chromosomal Material condences to form a compact mitotic chromosome. the necluar envolope degrades allowing the chromosomes to be free and the Centrsomes forms the mitotic spindle
2 of 7
describe what happens in metaphase
During metaphase the centosomes (With the mitotic spindle) are at opposite ends of the cell poles. the chromosomes are the lined up at the metaphase plate which is an imginary line equidistant between the two poles.
3 of 7
describe what happens in metaphase 2
The Chromatids of the chromosomes are all aligned with one another on the metaphase plate. the chromotids of each chromosome are attatched to a mitroyubules (which forms the spindle)
4 of 7
describe what happens in anaphase
During Anaphase the centrosomes with the mitroyubules will pull the duplicated chromosomes apart, ready for division. by the end of Anaphase, the two poles will have a complete set of chromosomes
5 of 7
describe what happens in telophase
Telophase is the last stage of mitosis. during telophase the mitroyubules pulls the chromosomes even closer to their poles and the nuclea envolope begins to form around the two poles
6 of 7
describe what happens during cytokinesis
the last phase of M phase is Cytokenisis, this is not a phase of mitosis byt follows after telophase were the cell actually divides into the two identical daughter cells
