ONS/ONCC Chemotherapy
Immunotherapy Certificate
Questions and Answers (100% Pass)
Lesson 1: Foundations to Set the Stage




The Normal Cell Cycle


→ -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


→ Cell division produces two identical cells through these two

major phases




During interphase:

→ 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)


→ -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)


→ -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)


→ -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


→ -G1 checkpoint

-S Phase




-G2 checkpoint




-M phase




Restriction Point


→ -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)
