G0 stands for
Growth zero
G1 stands for
Growth one
G2 stands for
Growth two
S1
Synthesis one
what happens during G0
start of a new cell
what happens during G1
builds the cytoplasm for a new cell
what happens during S1
makes a spare set of DNA (this DNA is not always used but is there just in case)
what happens during G2
preparing for mitosis
what is interphase
normal function of a cell
what is mitosis
cell replication
where does prophase happen
in the nucleus
what does DNA condense into
chromosomes
in prophase, what do chromosomes find
partners
what happens to the nuclear membrane during prophase
breaks down
what appears during prophase
spindle fibres
what replicates during prophase
the centrosome
what are the stages of interphase
Growth 0, Growth 1, Synthesis 1, Growth 2
what are the stages of mitosis
Prophase, Metaphase, Anaphase, Telophase
where do the centrosomes move during metaphase
to opposite sides (poles) of the cell
what forms between centrosomes during metaphase
spindle fibres
why are chromosomes aligned in the middle of the cell during metaphase
because of the tension of spindle fibres on either side
how are chromosomes attached to the spindle fibres in metaphase
through the centromere
where is the nucleus in metaphase
completely dissolved
what separates during anaphase
sister chromatids
