|
|
What are the phases in Interphase? |
G0 G1 - Gap phase S - Synthesis phase G2 - Gap phase |
|
|
What occurs in G0? |
Rest phase, no division. |
|
|
What occurs in G1? |
Gap phase - Cell increases in mass, G1 checkpoint |
|
|
What occurs in S phase? |
Synthesis phase - DNA synthesised. |
|
|
What occurs in G2? |
Gap phase - Cells increase in mass, protein synthesis, G2 checkpoint. |
|
|
What occurs in Prophase? (4) |
Chromatin condenses into discrete chromosomes Nucleolus disappears, nuclear envelope breaks down 2 centrosomes form mitotic spindles Spindle extends between opposite poles of cells |
|
|
What occurs in Metaphase? |
Spindle fully develops and chromosomes align Nuclear membrane fully disappears |
|
|
What occurs in Anaphase? |
Paired chromosomes (sister chromatids) separate and begin moving to opposite poles of the cell. |
|
|
What occurs in Telophase? |
Ident. sets of chromosomes at opp. poles, uncoil and revert to long, thin, thready chromatin. New nuclear envelope forms around each chromatin mass Nucleoi appear Mitotic spindle breaks up |
