EXAM 1 STUDY GUIDE
1. Cellular function primarily refers to which process?
A. Organ specialization
B. Tissue regeneration
C. Processes that maintain cell viability and activity
D. Hormonal regulation
Correct Answer: C
Rationale: Cellular function encompasses metabolic, structural, and regulatory processes
necessary for cell survival and normal activity.
2. Cancer is best defined as:
A. Benign cellular enlargement
B. Programmed cell death
C. Uncontrolled cell growth leading to tumor formation
D. Tissue inflammation
Correct Answer: C
Rationale: Cancer involves dysregulated cell division that escapes normal growth controls, often
forming tumors.
3. Genetic conditions are disorders caused by:
A. Environmental toxins
B. Lifestyle behaviors
C. Abnormalities in genes or chromosomes
D. Autoimmune reactions
Correct Answer: C
, ESTUDYR
Rationale: Genetic conditions arise from inherited or acquired alterations in DNA structure or
expression.
4. A single-gene disorder results from:
A. Multiple chromosomal deletions
B. Environmental exposure
C. Mutation in one specific gene
D. Abnormal immune response
Correct Answer: C
Rationale: Single-gene (monogenic) disorders are caused by alterations in one gene affecting
protein synthesis.
5. Autosomal dominant disorders are characterized by:
A. Requirement of two mutated alleles
B. X-linked inheritance
C. Expression with only one mutated gene copy
D. Skipping generations
Correct Answer: C
Rationale: A single dominant allele is sufficient to express the disorder, regardless of the second
allele.
6. Autosomal recessive disorders require:
A. One dominant gene
B. X chromosome mutation
C. Two copies of a mutated gene
D. Epigenetic activation
Correct Answer: C
Rationale: Recessive disorders manifest only when both alleles are mutated.
