Aim #47: What are the stages of mitosis?
Biology is the only subject in which multiplication is the same thing as
division…
1) What is mitosis?
Chromosomes Spindle Fibers
Mitosis is the process that divides the cell’s nucleus into two,each with a complete set of genetic material from the parent cell.
What are the phases of the CellCycle?
G1- Cells increase in size andsynthesize new proteins and organelles.
Cell Cell
What are the phases of the Cell Cycle?
S Phase- DNA (chromosomes) are replicated.
Centromere
Chromatid
What are the phases of the Cell Cycle?
G2 Phase- Many of the molecules and organelles for cell division areproduced.
Centriole
G1, S, and G2 Phases are collectively known as:
Interphase
What are the phases of the Cell Cycle?
M Phase- the cells undergo celldivision.
What does the “M” stands for?
Mitosis
The dance of the Chromosomes
Stages of Mitosis:Prophase:
1) The chromosomes becomevisible. (Condensation)
2) The centrioles separate andSpindle fibers begin to form.
3) The nuclear membrane breaksdown.Centriole
Spindle FibersNuclear
Membrane
Stages of Mitosis:Metaphase:
1) The chromosomes line upacross the center of the cell.
2) Each chromosome is connected toa spindle fiber at the centromere.
Stages of Mitosis:Anaphase:
1) The spindle fibers separatethe chromatids into individualchromosomes and they are moved apart.
Stages of Mitosis:Telophase:
1) The chromosomes gather at oppositeends of the cell.
2) Two new nuclear membranes form.
3) The chromosomes lose their distinctshapes.
Cytokinesis:
The cytoplasm pinches and two cellsare formed.
What is the end result of Mitosis?
46X 46X + 46X
Chromosome Number?
Parent Daughter Cell Daughter Cell
Is the genetic material of the daughter cells identical to the parent?
The same number ofchromosomes is maintainedfrom one generation to thenext.
YES
Mitosis Phases
Prophase Metaphase Anaphase
TelophaseCytokinesis
Which phase are these cells in?
Prophase Anaphase
What phase are these cells in?
Metaphase
Telophase
9) Animal vs. Plant Cell Mitosis
In plants, a Cell Plate forms across the middle of the cell.
