Lesson 1: Foundations to Set the Stage - (ANSWER)
Focusing on Cellular Structure and Function - (ANSWER)
The Normal Cell Cycle - (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 - (ANSWER)Cell division produces two identical
cells through these two major phases
During interphase: - (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) - (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) - (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) - (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 - (ANSWER)-G1 checkpoint
-S Phase
-G2 checkpoint
-M phase
Restriction Point - (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) - (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) - (ANSWER)-
Exceptions to this are those that are metabollically active, such as
-granulocytes
-and the epithelium of the GI tract
Cell Cycling Time - (ANSWER)Amount of time from mitosis to mitosis
Cell cycle video and image -
(ANSWER)http://highered.mheducation.com/sites/0072495855/student_view0/c
hapter2/animation__how_the_cell_cycle_works.html
Check points in the Cell Cycle: Keeping it All Under Control - (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
-These checkpoints monitor for DNA integrity and control progression through
mitosis
