Interphase

longest phase
"resting phase"
	misnomer
three sub-phases
	G1
	S
	G2
active period of Energy transformations
	photosynthesis
	respiration
G1
	1st growth phase
	active period of
		protein synthesis
		photosynthesis
		respiration
	1/2 length of interphase
S
	synthesis phase
	active period of protein synthesis
		making histones
	DNA replicates
		6ft long in each cell
		all DNA in body would
			fill a thimble
			stretch sun and back 400 times
G2
	2nd growth phase
	makes proteins
		microfilaments
			make spindle fibers
	store proteins needed in daughter cells
	prepare cell for mitosis
	make centriole
	"checklist phase"
