INTERPHASE (G1 - S - G2)

In between divisionsCells are in this phase most of the timeCan see nucleus DNA spread out as chromatin

Can’t see chromosomes DNA gets copied (S)

Cell gets ready to divide

PROPHASE1st dividing phase

Spindle fibers form & attach to chromosomes

Nuclear membrane & nucleolus disappear

DNA scrunches into chromosomes

Centrioles appear in centrosome region & move to poles
