Principles of Genetic Engineering starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Principles of Genetic Engineering.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
Describe one application of genetic engineering in agriculture.
Describe one ethical concern related to genetic engineering.
Describe the role of a vector in genetic engineering.
Describe the role of restriction enzymes in genetic engineering.
A researcher inserts a gene for drought resistance into a crop plant. After several generations, the trait is not observed in the offspring. Suggest one possible reason for this outcome.
A biotechnology company is developing a genetically engineered bacterium to clean up oil spills. What is the term for this application, and what is one potential risk associated with releasing such organisms into the environment?
A scientist wants to insert a gene from a jellyfish that causes fluorescence into a tomato plant. Explain the steps and tools required to achieve this, and discuss one challenge that might be faced during the process.
A researcher wants to produce a protein that is only active in the leaves of a genetically engineered plant. What genetic element should be included in the recombinant DNA to achieve this tissue-specific expression?
Which of the following best describes a 'vector' in genetic engineering?
(1) A virus that causes disease
(2) A tool used to transfer genetic material
(3) A type of cell
(4) A chemical used to stain DNA
Which of the following is a benefit of genetic engineering?
(1) Increased crop yield
(2) Decreased food production
(3) Reduced genetic diversity
(4) Increased disease in plants
Which of the following is a correct sequence of steps in genetic engineering?
(1) Isolation of gene → Insertion into vector → Transfer to host
(2) Transfer to host → Isolation of gene → Insertion into vector
(3) Insertion into vector → Isolation of gene → Transfer to host
(4) Isolation of gene → Transfer to host → Insertion into vector
Which of the following is a reason why bacteria are commonly used in genetic engineering?
(1) They have complex genomes
(2) They reproduce slowly
(3) They are easy to grow and manipulate
(4) They cannot take up foreign DNA
