15 Mitosis Flashcards
basic features of mitosis
DNA is replicated
chromosomes are condensed
DNA is distributed equally to daughter cells
diploid cells have 2 complete sets of chromosomes
sister chromatids
after replication but bef mitosis, the two identical copies of a chromosome remain associated
the stages of mitosis
S
G2
prophase
metaphase
anaphase
telophase
cytokinesis
S phase
DNA synthesis
G2
a gap with a checkpoint to ensure DNA synthesis is complete
prophase
chromosome condense
metaphase
chromosomes align
anaphase
chromosomes move to poles
telophase
nuclei re-form
cytokinesis
cell division and separation
open mitosis
the nuclear envelope breaks down and is re-formed after cytokinesis
closed mitosis
the nuclear envelope remains intact
cyclins
control the cell cycle
aneuploid cells
anaphase checkpoint fails - daughter cells do not inherit the correct number of chromosomes
