1.
A nursing student is reviewing disorders of cell growth. Which term is defined as a
disorder of altered cell differentiation and growth?
A. Hyperplasia
B. Neoplasia
C. Hypertrophy
D. Dysplasia
CORRECT ANSWER: B
Rationale: Neoplasia refers to the process of abnormal and uncontrolled cell growth and
differentiation, resulting in a neoplasm or new growth.
2.
The new growth resulting from neoplasia is called a:

BIOL 331
A. Lesion
B. Tumor
C. Neoplasm
D. Polyp
CORRECT ANSWER: C
Rationale: A neoplasm is the new, abnormal mass of tissue that results from
uncontrolled cellular proliferation.
3.
In the context of cell biology, proliferation is best defined as:
A. The process of cells becoming specialized
B. An adaptive process of new cell growth to replace old cells
C. The programmed death of cells
D. The invasion of surrounding tissues
CORRECT ANSWER: B
Rationale: Proliferation is the regulated process of cell division that allows for growth,
maintenance, and repair of tissues.
4.
Differentiation in cells refers to:
A. The rate of cell division

B. The process by which cells become more specialized
C. The ability to metastasize
D. The loss of cellular structure
CORRECT ANSWER: B
Rationale: Differentiation is the process through which cells mature and develop
specialized structures and functions.
5.
The correct sequence of the cell cycle phases is:
A. M Phase, G1, S Phase, G2
B. G1, S Phase, G2, M Phase
C. S Phase, G1, G2, M Phase
D. G2, M Phase, G1, S Phase
CORRECT ANSWER: B
Rationale: The standard cell cycle sequence is: G1 (growth), S Phase (DNA synthesis), G2
(preparation for division), and M Phase (mitosis).
6.
During the G1 phase of the cell cycle:
A. DNA synthesis occurs
B. The cell divides

C. DNA synthesis stops, and the cell enlarges and synthesizes RNA and proteins
D. Chromosomes condense
CORRECT ANSWER: C
Rationale: In G1, the cell grows, doubles its organelles, and synthesizes proteins and
RNA in preparation for DNA replication.
7.
DNA replication occurs during which phase of the cell cycle?
A. G1 Phase
B. S Phase
C. G2 Phase
D. M Phase
CORRECT ANSWER: B
Rationale: The S Phase (Synthesis Phase) is when DNA is replicated, resulting in two
identical sets of chromosomes.
8.
The G2 phase of the cell cycle is characterized by:
A. Cessation of all synthesis
B. Continued RNA and protein synthesis after DNA replication is complete
