prophase, metaphase, anaphase, telophase

Chromosomes become visable, nuclear envelop dissolves, spindle forms

Region of a chromosome where the two sister chromatids attach

Identical copies of a chromosome, attached at centromere, created during interphase S

Protein structures which move the chromosomes during cell division.

Located near the nucleus and help to organize cell division; location where spindle fibers originate

phase of mitosis in which the chromosomes line up across the center of the cell

Phase of mitosis in which the sister chromatids of the chromosomes separate and move to opposite ends of the cell

phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin

the result of cell division

result of mitosis

Division of the cytoplasm during cell division

new cells produced by cell division

In a plant cell, midline of dividing cells. Becomes the cell wall eventually.

the first sign of cytokinesis during cell division in an animal cell; a shallow groove in the cell surface near the old metaphase plate

cell grows

Period after DNA replication; cell prepares for division

Sister chromatids are produced

body cells

pre-planned cell death important during development

disorder in which some of the body's cells lose the ability to control growth

Chromosomes that have the same sequence of genes in the same order

A cell containing two sets of chromosomes (2n), one set inherited from each parent.

the process by which a cell becomes specialized for a specific structure or function.

proteins that regulate the timing of the cell cycle in eukaryotic cells

Allow the cell cycle to proceed only when certain events have occurred in the cell itself.

direct cells to speed up or slow down the cell cycle based on signals from outside the cell

special external regulatory proteins that stimulate the growth and division of cells during development

Cells that are capable of developing into most, but not all, of the body's cell types

A gene whose protein product inhibits cell division, thereby preventing the uncontrolled cell growth that contributes to cancer.

important regulators of the cell cycle that promote growth; alterations in the expression of these cells result in oncogenes which cause cancer
