actin
|
A globular protein that links into chains, two of which twist helically about each other, forming microfilaments (actin filaments) in muscle and other kinds of cells.
|
|
|
anaphase
|
The fourth stage of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell.
|
|
|
anchorage dependence
|
The requirement that a cell must be attached to a substratum in order to divide.
|
|
|
aster
|
A radial array of short microtubules that extends from each centrosome toward the plasma membrane in an animal cell undergoing mitosis.
|
|
|
Bacteria
|
One of two prokaryotic domains, the other being Archaea.
|
|
|
benign tumor
|
A mass of abnormal cells that remains at the site of its origin.
|
|
|
binary fission
|
A method of asexual reproduction by “division in half.” In prokaryotes, binary fission does not involve mitosis; but in single-celled eukaryotes that undergo binary fission, mitosis is part of the process.
|
|
|
cell cycle
|
An ordered sequence of events in the life of a cell, from its origin in the division of a parent cell until its own division into two; the eukaryotic cell cycle is composed of interphase (including G1, S, and G2 subphases) and M phase (including mitosis and cytokinesis).
|
|
|
cell cycle control system
|
A cyclically operating set of molecules in the eukaryotic cell that both triggers and coordinates key events in the cell cycle.
|
|
|
cell division
|
The reproduction of cells.
