CERTIFICATION EXAM OFFERED BY
NOCTI | Q&A WITH RATIONALES
1. What is the primary definition of agricultural
biotechnology?
A) The use of traditional farming methods to increase
crop yields
B) The manipulation of organisms or their parts to
create products that benefit agriculture
C) The study of soil composition and fertility
D) The application of mechanical engineering to farm
equipment
Correct answer: B
Rationale: Agricultural biotechnology involves using
scientific tools and techniques to modify living
organisms for agricultural purposes, including
improving crops, livestock, and food products.
2. The thread-like structures that exist in pairs and
carry genes are called:
A) Gametes
,B) Mitosis
C) Meiosis
D) Chromosomes
Correct answer: D
Rationale: Chromosomes are thread-like structures
located in the nucleus of cells that carry genetic
information in the form of genes.
3. Which of the following is an example of a traditional
biotechnology practice?
A) Genetic engineering of crops
B) Marker-assisted selection
C) Selective breeding of livestock
D) CRISPR gene editing
Correct answer: C
Rationale: Selective breeding is a historical
biotechnology practice that has been used for
thousands of years to develop desirable traits in
plants and animals.
4. Corn and cotton genetically modified to contain the
Bt toxin gene:
A) Are resistant to Round-Up® herbicide
,B) Decrease crop yields
C) Reduce the use of pesticides
D) Are generally less expensive than non-Bt crops
Correct answer: C
Rationale: Bt crops produce a protein toxic to certain
insects, reducing the need for chemical pesticide
applications.
5. An agronomist is primarily concerned with what
use of soil?
A) Construction
B) Acting as a filter for the hydraulic cycle
C) Supporting crop growth
D) Natural beauty
Correct answer: C
Rationale: Agronomy is the science of soil
management and crop production, focusing on using
soil to support and improve agricultural crop growth.
6. Which of the following is a fermented food
produced using bacteria?
A) Applesauce
B) Bologna
, C) Cheese
D) Toffee
Correct answer: C
Rationale: Cheese production involves bacterial
fermentation to convert milk into cheese, utilizing
microorganisms to develop flavor and texture.
7. DNA is extracted from cellular matter primarily to:
A) Study protein synthesis
B) Identify genetic traits and modifications
C) Produce antibiotics
D) Create new species
Correct answer: B
Rationale: DNA extraction allows scientists to
analyze genetic material for research, diagnostics,
and identifying specific genes or modifications.
8. Meat inspection is the governmental responsibility
of the:
A) U.S. Department of Agriculture (USDA)
B) Department of Homeland Security (DHS)
C) Occupational Safety and Health Administration
(OSHA)
