Stages of Cell Cycle
During what part of the cell cycle does the cell divide into two separate cells?
cytokinesis
Long, thin fibers of DNA (looks like spaghetti)
chromatin
List the phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase
Chromosomes before mitosis = 34 Chromosomes at end of mitosis in each cell = ?
34
A cell spends the majority of its time in what part of the cell cycle?
interphase
During what part of the cell cycle does DNA replication occur?
S phase of interphase
One half of a duplicated chromosome
sister chromatid
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide.
telophase
End result of mitosis (# and name)
2 identical daughter cells
The cell grows and carries out normal activities after division has occurred.
G1 phase of Interphase
Holds two sister chromatids together
centromere
Chromosomes are lined up on the cell's equator and centrioles are located at the poles.
metaphase
Times cell divides in each cell cycle.
1
What are the two main reasons that cells divide?
Growth and repair of an organism
The stage of the cell cycle that includes G1, S, and G2
interphase
Visible DNA structure seen beginning in prophase
chromosome
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides (poles) of the cell
prophase
How many nuclei does a cell in telophase have just before cytokinesis?
2
Animal cells use this to divide during cytokinesis.
cleavage furrow
Cell preparation for division occurs (post DNA replication)
G2 phase
What chromosomal structure do spindle fibers attach to on the chromosomes?
centromere
Chromatids are pulled apart and become individual chromosomes.
anaphase
How many chromatids in a chromosome?
2
Plant cells use this to divide during cytokinesis.
