Cell cycle

Study These Flashcards

A

Life cycle of a cell

Chromatin

DNA is unwound and wrapped around his tones

Chromosomes

DNA is wound up

Chromatid

Two sister chromatids make up one chromosome

Centromere

Holds the two sister chromatids together

Telomere

Each end of the chromosome that shorten each time it is copied

Histones

Protein around which the DNA winds up

G1

Gap 1 phase Growth phase Organelles increase in number

S-phase

Synthesis phase | DNA replication occurs

G2

Gap 2 phase More growth Centrioles form
