What is cytokinesis?
Division of cytoplasm
M phase means
Mitotic and cytokinesis

Walther Flemming develop and during ?
Dyes during mitosis and cytokinesis
Cell growth and copying of chromosomes
Interphase
What are the 4 stages of Mitosis
•Prophase
•Metaphase
• Anaphase
• telophase
How many stages Meiosis
8 stages
Hinay cell
Cell death
If cell is unstoppable what will occur?
Cell death
G1 and G2 phases stands for
Gap 1 and 2
G1 phase?
Enzymes development
G2 phase for?
Finalization
S phase stands for?
Synthesis
S phase for?
DNA replication
What is the main function of interphase
Cell finalize enzymes and ensure duplication of DNA
Chromosomes consisting of two sister chromatids shorter than microtubule
Early mitotic spindle
Development of early mitotic spindle
Prophase
prophase functions are?
•Chromosomes condensed
• in the cytoplasm, spindle fiber form
•Almost metaphase
•Example somatic/body cell
• not a major phase
Prometaphase
A protein but much longer than histone
Kinetochore
What is prometaphase?
Fragments of nuclear envelope, allows DNA to move inside
Apparatus of microtubules
Controls chromosomes movement during mitosis
Mitotic spindle
During prophase
Some spindle fiber attached kinetochore of chromosomes
Begin to move chromosomes
Kinetochores
Extend from each chromosomes
A radial array of short microtubules
Aster
The microtubule organizing center
During prometaphase
Assembly of spindle microtubules begins
Centrosome
