Question:
The ’cry’ gene transferred from Bacillus thuringiensis to a crop plant provides it with __________ properties.
The ’cry’ gene transferred from Bacillus thuringiensis to a crop plant provides it with __________ properties.
Show Hint
The cry genes code for toxins that kill insects.
Updated On: Nov 13, 2026
- herbicidal
- insecticidal
- fungicidal
- medicinal
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Bacillus thuringiensis makes Bt toxin proteins coded by cry genes.
Step 2: Effect in Plants
When the gene is transferred to a crop, the plant produces the toxin, which kills certain insect larvae.
Step 3: Conclusion
So the plant gets insecticidal properties.
Final Answer:
The cry gene gives insecticidal properties. \[ \boxed{\text{(B) }\text{insecticidal}} \]
