Mitosis Flashcards
1
Q
what is mitosis?
A
-nuclear division
-produce two identical daughter cells
-stages:
-prophase
-metaphase
-anaphase
-telophase
2
Q
prophase
A
-chromosomes condense
-nuclear envelope breaks down
-centrioles migrate to opposite poles of cell
-spindle fibres attach to chromosome centrimeres
3
Q
metaphase
A
-chromosomes moved by spindle fibres
-form metaphase plate across equator
4
Q
anaphase
A
-spindle fibres contract and shorten
-centromeres divide
-chromatids pulled to opposite sides if poles
-each half of cell receives one chromatid from each chromosme
5
Q
telophase
A
chromatids reach poles of the spindle
-begin to uncoil and become less distinct
-nuclear envelope starts to reform
