CELL REPRODUCTION: MITOSIS Flashcards
1 to 22nd chromosomes
Autosomes
Occurs in somatic cells
Mitosis
Results 2 identical daughter cells (diploid)
Mitosis
Phases of mitosis
Prophase
Prometaphase
Metaphase
Anaphase
Telophase
Telophase-cytokinesis
- longest phase
Prophase
- chromosomes starts to shorten and thicken
Prophase
Nucleolus gradually disappears (means cell is preparing for cell division
Prophase
- centrosome moves toward separate pole (mitochondria and other organelle, being removed)
Prophase
- between prophase and metaphase
Prometaphase
- preparation for metaphase
Prometaphase
- nuclear membrane degeneration and disappearance
Prometaphase
Nuclear envelope disintegrates so that the chromosomes?
Prometaphase
Would break free
It is a Protein complex found on the centromere
Attachment site of the spindle fiber
Kinetochore
Chromosomes are in its densest form (shortest structure)
Metaphase
Nuclear membrane completely disappears
Metaphase
Spindle fibers attach to kinetochore
Metaphase
Spindle fibers starts to shorten and goes back to the centrosome
Anaphase
Sister chromatids separates and moves toward the separate poles
Anaphase
Last stage of mitosis
Telophase
Arrival of chromatids towards the separate poles
Telophase
Nuclear membrane and nucleolus re-form
Telophase
Mitotic apparatus disappears
Telophase
Replication of chromosomal material
Telophase
*sister chromatid will make another chromatid so that the structure of the chromosome will be complete
Telophase
