Immunotherapy Certificate Questions
with Detailed Verified Answers
Question:Lesson 1: Foundations to Set the Stage
Ans:
Question: Focusing on Cellular Structure and Function
Ans:
Question: The Normal Cell Cycle
Ans: -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
Question: Interphase and Mitotic Phase
Ans: Cell division produces two identical cells through these two major phases
Question: During interphase:
, Page | 2
Ans: 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)
Question: First Growth Phase (G1 or first gap)
Ans: -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
Question: Synthesis Phase (S phase)
, Page | 3
Ans: -DNA replicates
-Results in the formation of identical pairs of DNA (chromatids)
-which are attached a t the centromere
-lasts 2-10 hours
Question: Mitotic Phase (M phase)
Ans: -Replicated chromosomes are aligned, separated, and move into 2 new,
identical daughter cells
-takes about 30-60 minutes
Question: Major points of cell regulation are entry and exit from
Ans: -G1 checkpoint
-S Phase
-G2 checkpoint
-M phase

Question: Restriction Point
Ans: -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
Question: G0 Phase (resting phase)
Ans: -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
Question: -Exceptions to this are those that are (Resting in G0 phase)
Ans: -Exceptions to this are those that are metabollically active, such as
-granulocytes
-and the epithelium of the GI tract
Question: Cell Cycling Time
Ans: Amount of time from mitosis to mitosis
