Term
Cell Division
Definition
The process by which a parent cell divides into two or more daughter cells.
Term
Interphase
Definition
The stage in cell cycle where the cell spends most of its time and prepares for cell division.
Term
Metaphase
Definition
The second stage of cell division during which the chromosomes become attached to the spindle fibers.
Term
Anaphase
Definition
The stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle.
Term
Stem Cells
Definition
The wildcard of all cells. They have the potential to develop into many different types of cells.
Term
Mitosis
Definition
A type of cell division that results in two daughter cells each the same as the parent nucleus, typical of ordinary tissue growth.
Term
Cell Cycle
Definition
The series of events that take place in the cell that lead to growth and reproduction.
Term
Cytokinesis
Definition
The division of cytoplasm following the division of the nucleus in a cell that results in two cells.
Term
Prophase
Definition
The first step in mitosis, where the spindles form two opposite poles.
Term
Telophase
Definition
Last stage in mitosis where chromosomes of daughter cells are grouped in new nuclei.
Term
Chromatid
Definition
Holds the replicated DNA of each individual chromosome.
Term
Centriole
Definition
Centrioles are protein based structures in animal cells that form spindle fibres which pull the chromosomes apart in mitosis to divide the cell.
Term
Cyclin
Definition
A class of proteins that fluctuate in concentration at specific points during the cell cycle and that regulate the cycle by binding to a kinase.
Term
Centromere
Definition
Region on a chromosome that joins two sister chromosomes.
Term
Spindle
Definition
Fibers of spindle pull the chromatids apart toward opposite poles.
Term
Cancer
Definition
Cells that grow and divide at a rapid, unregulated pace.
