Definition
3 phases:
G1- DNA unwinds and all the necessary proteins for DNA sysntheses are made
S- DNA unwinds and both strands are duplicated leading 2 2 sets of DNA
G2- All the stuctural proteins are made |

Term
What happens during Mitosis Prophase |
|
Definition
Nuclear envelope breaks
centrosomes go to each pole
Spindle fiber start pulling/ pushing the chromosomes to the middle
chromatin condenses into chromosomes |
|
|
Term
What happens during Mitosis Metaphase |
|
Definition
chromosomes line up in the middle |
|
|
Term
What happens during Mitosis Anaphase |
|
Definition
centromere breaks down and each sister chromatid is pulled to a centrosome |
|
|
Term
What happens during Mitosis Telophase |
|
Definition
nuclear envelopes reassembles and chromosomes spread out |
|
|
Term
What happens in meiosis Prophase I |
|
Definition
Nuclear envelope breaks down
Homologs form
start lining up
recombination of homologs
|
|
|
Term
What happens in meiosis Metaphase I |
|
Definition
homologous chromosomes line up at center |
|
|
Term
What happens during meiosis Anaphase I |
|
Definition
centrosomes start pulling a homolog to each centrosome |
|
|
Term
What happens during meiosis Prophase II |
|
Definition
centrosomes go the poles and form spinfdle fibers
then they start to line up at the middle |
|
|
Term
What happens during meiosis Metaphase II |
|
Definition
chromosome line up at the middle |
|
|
Term
What happens during meiosis Anaphase II |
|
Definition
chromosomes seperate at the centromere and start to get pulled to the centrosome |
|
|
Term
What happens during meiosis telophase |
|
Definition
nuclear envelope reassmebles
and chromosomebreak down into the nucleus |
