Cell cycle

cell cycle

sequence of events in which a body cell duplicates its contents and divides in two

Interphase

cell performs normal functions, prepares for division, and grows and creates copies of organelles and replicates DNA

Mitosis

process through which a cell divides genetic information into two identical copies within independent nuclei

Meiosis

produces sex cells and involves two cell divisions instead of one, produces four genetically unique cells

Mitotic phase

consists of nuclear division and cytoplasmic division to form two identical cells

Interphase

chromosomes double

Prophase

prepare: nuclear membrane dissolves

Metaphase

middle: chromosomes line up on the equator

Anaphase

apart: chromosomes are pulled apart

Telophase

two nuclei form

Cytokinesis

cytoplasm and organelles divide

G1 phase

The cell grows bigger, copies organelles, and makes proteins (8-10 hours)

S phase

DNA replicated (8 hours)

G2

cell growth continues; proteins and enzymes are synthesized; centrosome replication is completed (4-6 hours)
