Vocabulary
Cell Division
100
Division of one cell into two new cells.
What is cell reproduction?
100
The division of the nucleus.
What is mitosis?
100
Checkpoint that occurs before the cell copies its DNA. If conditions are favorable and cell is healthy it goes on to S (synthesis) phase.
What is G1 checkpoint?
100
Interphase
What are the first three phases of the cell cycle?
100
Phase that occurs after mitosis, pinching the (animal) cell in half.
What is cytokinesis?
200
Process that replaces dead and damaged cells and helps keep body healthy.
What is the purpose of cell reproduction in an adult organism?
200
The four phases of mitosis (in order).
What are the prophase, metaphase,anaphase and telophase?
200
Surrounding cells, surrounding organs and the environment signals what. (Hint: think of a cut on your skin)
What are 3 signals that usually make cells stop dividing?
200
Gene
What is a piece of DNA (which codes for RNA and protein)?
200
Circular piece of DNA.
What is prokaryotic DNA?
300
Cell size is limited by this -- making it difficult for substances to travel through the cell.
What is (large) surface area to volume ratio?
300
Structure that moves the chromatids to opposite poles during mitosis.
What are spindles?
300
The three cell regulation checkpoints in the cell cycle (in order).
What are G1, G2 and M (mitosis) checkpoints?
300
chromatin
What is a long strand of DNA that is condensed?
300
Cell division in Prokaryotes.
What is binary fission?
400
Identical pairs of chromatids that are held together at a centromere.
What are sister chromatids?
400
Phase of mitosis in which the chromosomes begin to condense and the nuclear membrane begins to dissolve.
What is prophase?
400
Treatments of this include chemotherapy, radiation therapy and surgery.
What are treatments for cancer?
400
Centromere
What is the structure where sister chromatids are separated from each other?
400
The two phases that make up cell division.
What is mitosis and cytokinesis?
500
A new cell produced by the division of a pre-existing cell.
What are daughter cells?
500
The repeated growth and division during the life of a cell.
What is the cell cycle?
500
Cells that invade and destroy nearby healthy cells & do not follow normal cell growth. Cells can break loose and spread to other parts of the body.
What is a malignant tumor?
500
Histone protein
What is the protein found in eukaryotic chromosomes (but not prokaryotic chromosomes)?
500
After cytokinesis (cell division), the new daughter cells enter the ____ phase of ___________ .
What is G1 phase of interphase?
