Question

In the nomenclature of restriction endonuclease it is essential to refer name of the ................

• A. place
• B. bacterium
• C. author
• D. procedure of its naming

Hint:

Restriction endonucleases are named based on the bacterium from which they are isolated, not the procedure or author.

Answer 1

The Correct Option is B

Step 1: Understanding the nomenclature of restriction enzymes.
In the naming of restriction enzymes, it is essential to refer to the bacterium from which the enzyme was isolated. This is because these enzymes are often named based on the genus and species of the bacterium.
Step 2: Analyzing the options.
(A) place: Incorrect — The place is not typically referenced in the naming of restriction endonucleases.
(B) bacterium: Correct — The bacterium is referenced when naming the restriction enzyme.
(C) author: Incorrect — The author is not involved in the naming convention of restriction endonucleases.
(D) procedure of its naming: Incorrect — The procedure is not specifically named in the enzyme's nomenclature.
Step 3: Conclusion.
The correct answer is (B) bacterium, as restriction enzymes are named after the bacterium from which they are isolated.
