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 |
