mitosis Flashcards
1
Q
what happens during prophase
A
- chromosomes condense making them more visible
- the nucleus breaks down making the chromosomes free floating in the cytoplasm
- the centrioles (bundle of proteins) begin to form spindle fibres
2
Q
what happens during metaphase
A
the chromosomes line up in the middle of the cell and attach to the spindle fibres
3
Q
what happens during anaphase
A
the spindle fibres contract and the chromosomes pull apart from their centromeres
this allows the chromatids to move to either end of the cell
4
Q
what happens during telophase
A
the chromosomes uncoil and the cytoplasm starts to split, two new nuclei form around the chromosomes
5
Q
what does mitosis create
A
2 genetically identical diploid cells - meaning it contains 2 complete sets of chromosomes (one from each parent)
6
Q
what type of cell undergos mitosis
A
somatic - all except sex cells
7
