Which response is the most accurate one-line answer for restriction enzyme at easy level?किस response में easy level के लिए restriction enzyme का सबसे सटीक one-line answer है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Bacterial enzyme that cuts a specific DNA sequencespecific DNA sequence को cut करने वाला bacterial enzyme
The governing concept is the basic definition of a restriction enzyme. In school-level biotechnology, a restriction enzyme is generally described as a bacterial enzyme that recognizes a particular DNA sequence and cuts the DNA at or near that site. This concise description includes both its biological source and its essential function, so option A is the most accurate one-line answer. The wording does not claim that every bacterial enzyme is a restriction enzyme; it identifies the relevant enzyme by its sequence-specific DNA-cutting activity. The other options describe unrelated functions of pigments, vitamins, or hormones and do not involve sequence-specific DNA cleavage.यहाँ मुख्य अवधारणा restriction enzyme की मूल परिभाषा है। विद्यालयी biotechnology में restriction enzyme को सामान्यतः ऐसे bacterial enzyme के रूप में बताया जाता है, जो किसी विशेष DNA sequence को पहचानकर उस site पर या उसके निकट DNA को काटता है। विकल्प A में इसका source और मुख्य function दोनों संक्षेप में दिए गए हैं, इसलिए यह सबसे सटीक one-line answer है। इसका अर्थ यह नहीं है कि प्रत्येक bacterial enzyme restriction enzyme होता है; पहचान sequence-specific DNA cutting से होती है। बाकी विकल्प plant pigment, vitamin और hormone के असंबंधित कार्य बताते हैं तथा DNA की विशिष्ट cutting से कोई संबंध नहीं रखते।
