Stages of interphase:
|
G1, S, G2, G0
|
|
G1
|
"gap"; transcription and translation
|
|
S
|
"synthesis"; replication of DNA
|
|
G2
|
transcription and translation;
2 identical copies of each DNA present in nucleus |
|
G0
|
cell in permanent interphase; stopped cycling; associated with specialized cells
|
|
4 characteristics of interphase (non-dividing cell):
|
a. chromosomes (DNA) uncoiled (not visible with light microscope)
b. centriole (animal cells) c. nuclear membrane intact d. nucleolus visible |
|
M phase consists of what 2 parts?
|
Mitosis and cytokinesis
|
|
Prophase
|
2. centrioles move apart
3. spindle (and aster) form 4. chromosomes attach to spindle fibers 5. nucleolus fades 6. nuclear membrane disintegrates |
|
Metaphase
|
chromosomes line-up along cell equator
|
|
Anaphase
|
centromeres uncouple
2. identical chromatids pulled apart and resultant chromosomes move to opposite poles |
|
Telophase
|
("prophase in reverse")
|
|
Cytokinesis
+ Name in animal vs plant cell |
division of the cytoplasm
Animal: Cleavage Furrow Plant: Cell Plate |
