CERTIFICATE EXAMINATION TEST
VERIFIED QUESTIONS AND SOLUTIONS
GRADED A+
●● 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
