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"
