Cell cycle Flashcards
interphase
cell growths and copies DNA
mitotic phase
cell separates DNA in two sets
divides cytoplasm
phases of interphase
G1 - S - G2
G1 phase
cell grows
organelles replicate
S phase
copies genetic material –> but still only one chromsome
G2 Phase
cell grows
DNA checked for errors
energy stores increased
prophase
DNA in condensed form
centrosomes wander to opposite side of cell
nuclear membrane starts to break down
metaphase
chromosomes get lined up by microtubuli
anaphase
centromeres divide –> 4 chromosomes
chromosomes pulled to other side of cell
telophase
nuclear envelope forms around chromosomes
chromosomes unwind
–> DNA return to chromatin form
cytokinesis
cell divides
meiosis
reduction division
alleles
different version of same gene
fertilised egg
zygote
sex cells
gametes
