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
After cytokinesis happens what is the relationship between the new and old cell?
They are clones of each other
Chromosomes meet in the middle on spindle fibers
Metaphase
During G1 of Interphase, what is the cell doing?
Cell Growth
What are the two longest phases of the cell cycle?
Interphase and Mitosis
What phase of the cell cycle splits the DNA in the nucleus?
Mitosis
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 an example how our body uses mitosis.
Healing cuts, growing, nails and hair
What are the 3 steps of Interphase?
G1, S, G2
During what step does the copied DNA condense into chromosomes?
Prophase
How do mitosis and meiosis differ?
Mitosis creates cells that are clones of each other.
Meiosis creates cells that have genetic variation
In what phase do the cytoplasm and organelles split into two cells?
Cytokinesis
Unregulated cell division leads to what disease?
Cancer
In which step are two nuclei present?
Telophase
In this step, centrioles are formed.
G2
During the S step of interphase, what is the cell doing?
copying DNA
What is cell death called?
Apoptosis
What disappears during prophase?
The nucleus / nuclear membrane / envelope
What is the purpose of the cell cycle in wounds?
Cell and tissue repair
What are the 3 phases of the cell cycle?
Interphase, Mitosis, Cytokinesis
How do sexual and asexual reproduction differ?
Asexual reproduction creates offspring that are clones.
