mitosis Flashcards
(8 cards)
1
Q
chromatids
A
replicates of chromosomes
2
Q
why are daughter cells produces through mitosis?
A
asexual reproduction
growth
tissue repair
3
Q
stages of mitosis
A
prophase
metaphase
anaphase
telophase
4
Q
prophase
A
chromatids shorten and DNA thickens
nuclear envelope breaks down
centriole divides and move to opposite ends
spindle fibres form
5
Q
Metaphase
A
chromatids attach to spindle threads
attach by centromeres
6
Q
anaphase
A
centromeres split
motor proteins pull each sister chromatid to opposite poles
chromosomes assume v shape
7
Q
telophase
A
chromosomes reach poles
new envelope surrounds them
cell contains two nuclei
8
Q
how cytokinesis is done
A
in animal cells plasma membrane folds inward and nips the cytoplasm
in plant cells plate forms and cell membrane and wall are formed here
