The Normal Cell Cycle - CORRECT ANSWER- -The cell cycle refers to the ordered seres of
processes of DNA replication and mitosis, or cell division
-Cell nucleus regulates these processes by gathering and processing complexes
molecular information
Interphase and Mitotic Phase - CORRECT ANSWER- Cell division produces two identical
cells through these two major phases
During interphase: - CORRECT ANSWER- Cell grows and DNA is replicated through the
following three steps:
1: First growth phase (G1 or first gap)
,2: Synthesis phase (S phase)
3:Mitotic Phse (M phase)
First Growth Phase (G1 or first gap) - CORRECT ANSWER- -cells increase in size
-reproduce RNA
-"quality assurance" test that the cell will be ready to synthesis DNA
-Length of time is variable, can be from hours to days
Synthesis Phase (S phase) - CORRECT ANSWER- -DNA replicates
-Results in the formation of identical pairs of DNA (chromatids)
-which are attached a t the centromere
-lasts 2-10 hours
Mitotic Phase (M phase) - CORRECT ANSWER- -Replicated chromosomes are aligned,
separated, and move into 2 new, identical daughter cells
,-takes about 30-60 minutes
Major points of cell regulation are entry and exit from - CORRECT ANSWER- -G1
checkpoint
-S Phase
-G2 checkpoint
-M phase
Restriction Point - CORRECT ANSWER- -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 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
G0 Phase (resting phase) - CORRECT ANSWER- -After mitosis, cells may enter back into
the G1 phase or go into a resting phase, known as G0
, -Most cells in the human body reside in G0
-Exceptions to this are those that are (Resting in G0 phase) - CORRECT ANSWER- -
Exceptions to this are those that are metabollically active, such as
-granulocytes
-and the epithelium of the GI tract
Cell Cycling Time - CORRECT ANSWER- Amount of time from mitosis to mitosis
Cell cycle video and image - CORRECT ANSWER-

nimation__how_the_cell_cycle_works.html
Check points in the Cell Cycle: Keeping it All Under Control - CORRECT ANSWER- -The
cell cycle is carefully controlled through a series of checkpoints
-Variation in duplication or distribution of chromosomes during cell division can
alter the genetic information passed on to daughter cells, leading to cellular
dysfunction and disease, such as cancer
