Certificate LATEST EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS |GRADED A
2024

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

DNA Damage Checkpoints Correct Answer: -If DNA damage is present, cells are

programmed to stop dividing or undergo apoptosis (programmed cell death)



-The retinoblastoma protein (Rb), p53, and p21 are some of the most well-understood

inhibitory proteins (IP)



Inhibitory proteins p53 Correct Answer: -Levels of this IP regulate several important

target genes



-Will increase when DNA damage is present

,-Protects against inappropriate signal proliferation



-sometimes called the "suicide gene"



M Phase Checkpoints Correct Answer: When the cells prepare to divide, the

chromosomes line up in the mitotic spindle.



If the chromosomes are not properly aligned, division is not allowed to continue



Immunity Correct Answer:



Cells of the Immune System Correct Answer:



Pluripotent Stem Cell Correct Answer: -The cells of the immune system are created in

the bome marrow from what is know as a ___



-A stem cell that can differentiate into any cell type except for extraembryotic tissue,

does not yet have a function



Myeolid Precursor Cells Correct Answer: Mature into:

-RBCS

-Plts

-WBCs (Granulocytes)

,Lymphoid Precursor Cells Correct Answer: Mature into:

-Specialized WBCs called lymphocytes (Agranulocytes)



Lines of Defense: The Immune System's Response to Attack Correct Answer: Consists

of 2 types of immunity:



1: Innate

2: Adaptive




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
