Chapter 10.2 Cell Division Flashcards
Mitosis
First stage; division of the cell nucleus
What are the two stages in cell division in an eukaryotic cell?
Mitosis and cytokinesis
Cytokinesis
Second stage; division of the cytoplasm
What does the chromosomes carry?
The DNA , coded genetic information, and proteins
Chromatids
One of the identical “sister” parts of a duplicated chromosome
Centromere
Area where the chromatids of a chromosome are attached.
Interphase
Period of cell cycle between cell division
Cell cycle
The series of events that cells go through as they grow and divide
What happens during the cell cycle?
A cell grows , prepare for division, and divides to form two daughter cells, each of which then begins the cycle again.
What are the four stages of the cell cycle?
- M phase
- S phase
- G1 phase
- G2 phase
What takes place during the M phase?
Mitosis and Cytokinesis
During what phase when chromosome replicate?
S phase
What phases are between M phase and S phase?
G1 and G2 phase
What does the G stands for?
Gap
Which phase does the cell do most of their growing?
G1 phase
What phase is the shortest of the three phases?
G2 phase
What happens during the G2 phase?
Organelles and molecules are produced
What are the four stages of mitosis?
Prophase, Metaphase, Anaphase, and Telophase.
Centrioles
Two tiny structures located in the cytoplasm near the nuclear envelope.
Spindle
A fanlike microtubule structure that helps separate the chromosomes
What phase is the longest?
Prophase
During what phase does the chromosome line up across the center of the cell?
Metaphase
During what phase does the centromeres that join the sister chromatids split, allowing the sister chromatid to separate and become individual chromosomes?
Anaphase
During what phase does the chromosome begin to disperse into a tangle of sense material
Telophase
What usually takes place at the same time as telophase?
Cytokinesis
