Basics of Biotechnology
. What is biotechnology?
The use of living organisms or their systems to make useful products for humans.
What is the name of the most widely used gene editing tool?
CRISPR-Cas9.
Why are livestock often vulnerable to infectious diseases?
Because they are kept in close contact and pathogens spread easily.
How does gene editing improve farm productivity?
By increasing animal health and growth efficiency.
What branch of biotechnology deals with improving living organisms for human benefit?
Applied biotechnology.
What does CRISPR-Cas9 do in gene editing?
It cuts and modifies specific parts of DNA.
Name one bacterial or viral disease in cattle or pigs.
Foot-and-mouth disease
2. Why can disease-resistant animals reduce costs for farmers?
Less money is spent on treatment and veterinary care.
Why is DNA used for in living organisms?
It stores genetic information.
What molecule carries genetic information that is edited?
DNA
What is the purpose of making animals disease-resistant?
To reduce illness and improve survival rates.
How does gene editing help food security?
It increases reliable food production.
What is genetic modification?
Changing an organism’s DNA to give it new or improved traits.
What is a “guide RNA” used for in CRISPR?
It directs Cas9 to the correct DNA target.
How might gene editing change agriculture in the future?
It may create more disease-resistant and efficient livestock.
What is one environmental benefit of healthier livestock?
Reduced use of antibiotics and lower waste from dead animals.
