INTRODUCTION
The ASCP CG Certification exam evaluates competency in cytogenetics and molecular
genetics within clinical laboratory settings. It assesses foundational knowledge, analytical
skills, and the ability to apply laboratory techniques to real-world diagnostic scenarios.
Candidates must demonstrate proficiency in chromosome analysis, molecular testing,
quality assurance, and regulatory compliance. The exam consists of multiple-choice and
scenario-based questions designed to test decision-making, interpretation of results, and
,adherence to professional standards. Emphasis is placed on accuracy, ethical responsibility,
and effective problem-solving in laboratory environments.
SECTION 1: QUESTIONS 1–35
1. Which phase of the cell cycle is optimal for chromosome analysis in cytogenetics?
A. G1 phase
B. S phase
🔴 C. Metaphase
D. Telophase
🔵 Explanation: Chromosomes are most condensed and visible during metaphase,
making it ideal for karyotyping.
2. What is the primary purpose of Giemsa staining in cytogenetics?
A. DNA amplification
🔴 B. Chromosome banding
C. Protein detection
, D. RNA sequencing
🔵 Explanation: Giemsa staining produces characteristic banding patterns used to
identify chromosomes.
3. Which technique is used to detect specific DNA sequences using fluorescent probes?
A. PCR
B. Southern blot
🔴 C. FISH
D. ELISA
🔵 Explanation: Fluorescence in situ hybridization (FISH) uses labeled probes to
detect specific DNA sequences.
4. A trisomy condition indicates:
A. Loss of a chromosome
🔴 B. Presence of an extra chromosome
C. Chromosome inversion
D. Chromosome deletion
🔵 Explanation: Trisomy refers to three copies of a chromosome instead of two.
