Term
G1 (gap 1)
Definition
First stage of the cell cycle. Increase in size and must pass a checkpoint. cells spends the most time in this stage
Term
G2 (gap 2)
Definition
Third stage of the cell cycle. Additional growth occurs and must pass a checkpoint.
Term
S (synthesis)
Definition
Second stage of the cell cycle. During this stage, cells make a copy of its nuclear DNA. Contains two complete sets of DNA by the end
Term
M (mitosis)
Definition
Fourth stage of the cell cycle. Includes Mitosis and Cytokinesis
Term
Mitosis
Definition
Is the division of the cell nucleus and its contents
Term
Prophase
Definition
DNA and proteins condense into tightly coiled chromosomes. The nuclear envelope breaks down,centrioles begin to move to opposite poles and spindle fibers begin to form
Term
Metaphase
Definition
Spindle fibers begin to attach to each chromosome. They align the chromosomes along the cell equator
Term
Anaphase
Definition
Chromatids separate to opposite sides of the cell. Cytokinesis usually begins in late anaphase or telophase
Term
Telophase
Definition
Nuclear membranes start to form, chromosomes begin to uncoil, and the spindle fibers fall apart
Term
Cytokinesis
Definition
Divides cytoplasm between two daughter cells, each with a genetically identical nucleus. The cells enter interphase and begin the cycle again.
Term
DNA
Definition
molecule that stores genetic information in all organisms
Term
Centrioles
Definition
small cylinder-shaped organelle made of protein tubes arranged in a circle; aids mitosis
Term
Cancer
Definition
common name for a class of diseases characterized by uncontrolled cell division
Term
Malignant
Definition
cancerous tumor in which cells break away and spread to other parts of the body, causing harm to the organism's health
Term
Carcinogen
Definition
substance that produces or promotes the development of cancer
Term
Benign
Definition
having no dangerous effect on health, espeically referring to an abnormal growth of cells that are not cancerous
