Before the cells divides, it must synthesize biochemical and other contents. Divided into 3 parts
when DNA synthesis occurs; replicates its DNA and centrioles
S phase (interphase)
cell will grow and synthesize materials needed for the S phase
G1 phase (interphase)
Cell completes growth and production of enzymes
G2 phase (interphase)
Chromosomes condense and become visible. Spindles form
Chromosomes align in the middle.
Spindle fibers contract and pull the sister chromatids to opposite poles of cell. Each pole has an identical set of genes.
