Module 2
Finals Exam (Qns & Ans)
2025
General Instructions
1. Read All Questions Carefully: Make sure you understand each question.
2. Time Management: You have a specific amount of time to complete the exam.
Keep an eye on the clock and pace yourself.
3. Allowed Materials: Only use materials that are explicitly allowed. Unauthorized
materials can lead to disqualification.
4. ANS Format: Follow the required format for your ANS. For example, multiple-
choice questions might need you to select the best ANS, while essay questions
require detailed responses.
5. Academic Integrity: Adhere to the university's honor code. Any form of cheating or
plagiarism is strictly prohibited.
6. Technical Requirements: Ensure your computer and internet connection are
stable. For online exams, you might need a webcam and microphone for proctoring
purposes.
7. Submission: Submit your ANS before the time expires. Late submissions might
not be accepted.

,1. Which of the following statements regarding tumor
suppressor genes is correct?
a) They are involved in promoting cell division.
b) Loss of function mutations in these genes lead to cancer.
c) They are considered proto-oncogenes.
d) They always function as oncogenes when mutated.
Correct ANS: b
Rationale: Tumor suppressor genes inhibit cell division;
mutations that lead to their loss can result in uncontrolled cell
proliferation.
2. The hallmark of cancer defined by sustained proliferative
signaling is largely attributed to which mechanism?
a) Mutations in tumor suppressor genes
b) Activation of oncogenes
c) Telomere shortening
d) Immune evasion
Correct ANS: b
Rationale: Oncogenes lead to continuous signaling for cell
division, a core characteristic of cancer.

,3. Which biomarker is most commonly associated with
colorectal cancer?
a) PSA
b) CA-125
c) CA 19-9
d) AFP
Correct ANS: c
Rationale: CA 19-9 is a tumor marker commonly elevated in
colorectal cancer.
4. In which phase of the cell cycle does DNA damage repair
primarily occur?
a) M phase
b) G1 phase
c) S phase
d) G2 phase
Correct ANS: d
Rationale: The G2 phase is when the cell prepares for mitosis
and DNA repair processes are most active.

, 5. The cancer cachexia syndrome is primarily characterized by
which of the following?
a) Increased appetite
b) Weight gain
c) Muscle wasting and anorexia
d) Elevated blood pressure
Correct ANS: c
Rationale: Cancer cachexia involves loss of muscle mass
(wasting) and decreased appetite (anorexia).
Fill-in-the-Blank Questions
6. The process by which cancer cells spread to distant sites in the
body is known as __________.
Correct ANS: metastasis
Rationale: Metastasis refers to the spread of cancer from its
primary site to other parts of the body.
7. The term used to describe tumor growth patterns that indicate
a better prognosis typically is __________.
Correct ANS: benign
