Lesson 1: Foundations to
Set the Stage
Focusing on Cellular
Structure and Function
-The cell cycle refers to the ordered seres of
processes of DNA replication and mitosis, or cell
division
The Normal Cell Cycle
-Cell nucleus regulates these processes by gathering
and processing complexes molecular information
Interphase and Mitotic Cell division produces two identical cells through
Phase these two major phases
Cell grows and DNA is replicated through the
following three steps:
1: First growth phase (G1 or first gap)
During interphase:
2: Synthesis phase (S phase)
3:Mitotic Phse (M phase)

-cells increase in size
-reproduce RNA
First Growth Phase (G1 or
first gap) -"quality assurance" test that the cell will be ready to
synthesis DNA
-Length of time is variable, can be from hours to days
-DNA replicates
-Results in the formation of identical pairs of DNA
(chromatids)
Synthesis Phase (S phase)
-which are attached a t the centromere
-lasts 2-10 hours
-Replicated chromosomes are aligned, separated, and
move into 2 new, identical daughter cells
Mitotic Phase (M phase)
-takes about 30-60 minutes
-G1 checkpoint
Major points of cell -S Phase
regulation are entry and
exit from -G2 checkpoint
-M phase

-The transition from the resting phase into an actively
dividing phase (G0-G1) is a point where cellular
transformation can occur
-During this time, cells pass through a transition phase
Restriction Point
known as a restriction point
-Extracellular growth factors trigger reentry into G1,
and GF are required to send the cells past the
restriction point, or the point of no return
-After mitosis, cells may enter back into the G1 phase
or go into a resting phase, known as G0
G0 Phase (resting phase)
-Most cells in the human body reside in G0
-Exceptions to this are those that are metabollically
active, such as
-Exceptions to this are
those that are (Resting in
-granulocytes
G0 phase)
-and the epithelium of the GI tract
Cell Cycling Time Amount of time from mitosis to mitosis
