Mitosis Flashcards
refers to how a cell divides to produce new cells.
Mitosis
Only ——– undergo mitosis
Somatic
The cell undergoes mitosis if it is a somatic cell or meiosis if it is a sex cell.
It allows the cell to divide and produce new cells.
M-phase
In preparation for mitosis, these checkpoints check for errors
Cell Cycle Checkpoint
Checks for Cell size and DNA replication
G2 checkpoint
Checks for chromosome spindle attachment
Metaphase checkpoint
Checks for nutrients, growth factors, and DNA damage
G1 checkpoint
DNA in interphase is found in the form of ———— which condenses during mitosis.
Chromatin
Each chromosome is made up of…
Sister Chromatids
The number of sets of chromosomes that a cell or an organism has is known as
Ploidy
The resting state
G0
Phases of Mitosis
Prophase, Metaphase, Anaphase, Telophase
*The chromatin condense into chromosomes.
*The nucleolus disintegrates.
*The mitotic spindle starts to form.
Prophase
*It begins after the nuclear envelope breaks down.
*The centrosomes move to opposite poles.
*The kinetochores found at the centromeres become apparent
Prometaphase
The microtubules of the mitotic spindle attach and interact with the kinetochores of the chromosomes.
The chromosomes align at the center of the cell, in the metaphase plate.
Metaphase
