Mitosis Flashcards
Interphase is cell ___ an DNA ____
growth, replication
What are chromosomes?
long continuous thread of DNA
What are the 3 subphases in interphase?
G1 phase, S phase, and G2 Phase
G1 Phase is when cells grow and make proteins
True
G1 - Gap 1 Phase
S phase is when more cells grow and make proteins
False
S phase is when DNA replication occurs
S - Synthesis Phase
G2 Phase is when DNA replication occurs
False
G2 Phase is when more cells grow and make more proteins
G2 - Gap 2 Phase
What is the acronym for the phases of Mitosis?
PMAT
What are the phases of Mitosis (in order)?
Prophase, Metaphase, Anaphase, and Telophase
In Prophase…
(Prepare)
Chromosomes condense & are visible as chromatids
nucleus disappears
Spindle fibers form out of centrioles
Genes are
A section of DNA for making proteins
People have 46 chromosomes
True
The parents give the offspring 46 chromosomes each
False
The parents give the offsprings 23 chromosomes to equal 46
Chromatid
1/2 of a duplicated chromosome
Sister Chromatids…
Two identical chromatids
Centromere
region of the condensed chromosomes that looks pinched
Telomere
Ends of the DNA molecule
In Metaphase…
(Middle)
Spindle fibers connect to centromeres
Chromosomes line up in the center of cell
In Anaphase
(Attach/away)
Chromatids seperate to individual chromosomes
Moves to opposite ends
In Telophase
(Twins)
Chromosomes condense and looks like chromatin
Nucleus re-forms
Spindle fibers breaks down
In Cytokinesis (Plants)
Cell plate forms between nuclei and turns into the cell membrane
In Cytokinesis (Animals)
Cleavage furrow forms that pinches the cell into 2 equal parts
The entire cycle of Mitosis…
Interphase, Mitosis, Cytokinesis
The subphases of Interpahse `
G1 Phase, S phase, G2 Phase
The subphases of Mitosis
Prophase, Metaphase, Anaphase, and Telophase
Last stage of Mitosis
Cytokinesis
Cells divide every 2 years
False
Cell divide at different rates based on its needs
Cell cycle is controlled by a chemical control system
true
At the end of Mitosis there are two ___ cells
Diploid
The scientific name for the cells created at the end of Mitosis
Somatic Cells
Mitosis creates…
Identical cells for growth
Mitosis goes through 2 divisions
False
Mitosis grows through 1 division
