cell division

the process by which a cell divides into two new daughter cells

sister chromatids

two identical cells

interphase

the "in-between" period of growth

G1 Phase

cells do most of their growing

G2 Phase

when DNA is replicated the cell enters this phase, many organelles and molecules required for cell division are produced

S Phase

key proteins associated with the chromosomes are synthesized during this phase

mitosis

part of the eukaryotic cell division during which the cell nucleus divides

interphase

the cell grows and replicates its DNA and centrioles

prophase

the chromatin condenses into chromosomes. the centrioles seperate, and a spindle begins to form. The nuclear membrane breaks down

metaphase

the chromosomes line up across the center of the cell. Each chromosome is connected to a spindle fiber at its centromere

anaphase

the sister chromatids seperate into individual chromosomes and are moved apart

telophase

the chromosomes gather at opposite ends of the cell and lose their distinct shapes. Two new nuclear membranes form.

cytokinesis

the cytoplasm pinches in half. Each daughter cell has an identical set of duplicate chromosomes

centrioles

two tiny structures located in the cytoplasm near the nuclear envelope

spindle

a fanlike microtuble structure that helps separate the chromosomes

internal regulators

proteins that respond to events within the cell

external regulators

proteins that respond outside the cell

cancer

uncontrolled cell growth
