Cell Cycle 1
When do cells replicate their DNA?
S phase
When are chromosomes pulled apart toward the opposite side of the cell?
Anaphase
What does PMAT stand for?
Prophase, Metaphase, Anaphase, Telophase
Which type of cell is pluripotent (unprogrammed)?
Stem cell
Chromosomes meet in the middle on spindle fibers
Metaphase
During G1 of Interphase, what is the cell doing?
Cell growth and copying organelles.
What are the two main parts of the cell cycle?
If a cell with 36 chromosomes undergoes mitosis, how many cells will be produced and how many chromosomes will be in each cell?
2 cells with 36 chromosomes each
What is one reason that cells go through the process of mitosis?
To replace old cells, for growth or for repair
During the mitotic phase, what is the order of the phases
Prophase, metaphase, anaphase, and telophase
Give 2 examples how our body uses mitosis.
Repair and growth
What word describes a cell that has half the set of chromosomes?
Haploid
During what phase does the copied DNA condense into chromosomes?
Prophase
What is the name of the process when chromosomes swap genes in order to increase genetic variability?
Crossing Over
In what phase do the cytoplasm and organelles split into two cells?
Cytokinesis
Unregulated cell division leads to what disease?
Cancer
In which phase are two nuclei present?
Telophase
What process creates four daughter cells?
Meiosis
During the S phase of interphase, what is the cell doing?
coping DNA
What is cell death called?
Apoptosis
What disappears during prophase?
The nucleus / nuclear membrane / envelope
How many chromosomes are in a diploid skin cell on a human?
46 chromosomes
What is the purpose of checkpoints?
Check the cell or DNA for mistakes
Nuclear membranes return around DNA
Telophase
