Mitosis
the division of the nucleus
Chromosomes
found in the nucleus, chromosomes are composed of DNA
Spindle
spindle fibers pull the chromatids to opposite poles during mitosis
Interphase
(not a part of mitosis) cell grows and organelles divide
Prophase
the chromatin condenses into chromosomes and spindle fibers start to form
Metaphase
the chromosomes line up in the middle of the cell, and the spindles attach
Anaphase
the chromatids seperate and the spindels pull the chromatids towards the poles
Telophase
the chromatids begin to unwind and the nuclear envelopes form
Cytokinesis
(not a part of mitosis) the cytoplasm divides, producing two identical daughter cells
Mitosis in plant cells v. animal cells
in cytokenisis for plants a cell plate forms and in animal cells a clevage burrow forms
Cell cycle
the time during which a cell grows, prepares for division, and divides to form two cells
G1 Phase
cell grows and gets larger
S Phase
synthesis=replication of choromosomes
G2 Phase
replication of organells and growth
M Phase
cell division
Checkpoints
(before s, before m, and before the end of m) there the cell checks to make sure no fatal errors have occured, if so, they fix them
Binary fission
the cell replication of prokaryotes:
1. dupilcation of chromosomes(separate masses)
2. Elongation
3. Division
