Question:
The source of restriction endonuclease Alu I is ________ .
The source of restriction endonuclease Alu I is ________ .
Show Hint
The name of a restriction enzyme comes from the genus and species of its source.
Updated On: Nov 12, 2026
- Agrobacterium tumefaciens
- Arthrobacter luteus
- Escherichia coli
- Bacillus thuringiensis
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
A restriction enzyme name takes the first letter of the genus, the first two letters of the species, then the strain, and a Roman numeral for the order of isolation.
Step 2: Decode Alu I
In Alu I, A stands for Arthrobacter, lu stands for luteus, and I means it was the first enzyme isolated from this organism.
Step 3: Conclusion
So the organism is Arthrobacter luteus, which is option B.
Final Answer:
Alu I is obtained from Arthrobacter luteus. \[ \boxed{\text{(B) }\textit{Arthrobacter luteus}} \]
