H Bio - Mitotic Phase of the Cell Cycle

chromatin

dna wrapped around proteins

chromosomes

made of chromatin and contains genes

chromatids

exact copies of a chromosome

centromere

location where chromatids are held together

centrosome

organelle that develops spindle fibers

centriole

center of the centrosome

cytokinesis

splitting of the cells cytoplasm

prophase

chromatin separates into sister chromatids; mitotic spindle begins to form

metaphase

cell's duplicated chromosomes are lined up between poles of mitotic spindle

anaphase

sister chromatids separate; complete sets of daughter chromosomes at poles of cells

telaphase

daughter nuclei forms at pools during cytokenisisG

G1

grow and mature

G0

do not divide (neurons, red blood cells, muscles)

S phase

copy DNA

G2

prepare for division

M phase

mitosis (splitting of cell)
