Lesson 1: Foundations to Set the Stage - (Correct Answer)


Focusing on Cellular Structure and Function - (Correct Answer)



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

Check points in the Cell Cycle: Keeping it All Under Control - (Correct Answer)-The cell cycle
is carefully controlled through a series of checkpoints



还是指某个特定的词或概念

？

, -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



Progression through the cell cycle is controlled through two proteins: - (Correct Answer)1.
cyclines (D, E, A, B)



2. Cyclin-dependent kinases (CDKs)



-Cyclin-CDK complex allows the cell to progress through each phase of the cell cycle


Locations of proteins Cyclins (D, E, A, B) and CDKs - (Correct Answer)-(G0-G1) : Cyclin D
and CDK 4/6



-Early S: Cyclin E and CDK 1/2



-Late S: Cyclin A and CDK 1/2



-G2: CDK 1/2 and cyclin A


-Before M: CDK 1 and Cyclin B



Inhibitory proteins - (Correct Answer)-prevent progression of the cycle when DNA damage is
detected



-An example of an inhibitory protein is p53 (AKA TP53)
