Cell Division Vocab

Make copies of self

Two join together to make a chromosome

Where the chromatids are joined

Cell Growth

Copying DNA, making proteins

Getting ready to divide

Dividing

When the nucleus splits

When the cytoplasm splits

chromatin condenses into chromosomes, centrioles separate, longest phase, spindle fibers attach to chromosomes, nuclear membrane breaks down

Microtubule structure that forms at poles and makes chromosome separation easier

Chromosomes line up along center, separate, but not at centromere

Chromosomes separate at centromere, and move along spindle fibers to poles

Chromosomes disperse, two new nuclear membranes form, spindle breaks apart

Scatter

Forms between the nuclei in a plant cell and becomes the cell wall

one parent, parent and offspring are genetically identical, allows numbers to increase rapidly

Two parents, each parent contributes 1 set of chromosomes, allows much greater variety

Genetic information storage, made of DNA, located on chromosomes, alleles

Different forms of one gene

Two sets of chromosomes

Sex cells, divide by meiosis

Contains 1 set of chromosomes

Match in every member of a species

A pair of homologous chromosomes (4 chromatids)

When 2 homologous chromosomes exchange parts of their chromatids, making new alleles
