Restriction digest gel tank में buffer spill हो जाए तो क्या करना चाहिए?
What should be done if buffer spills around gel tank in restriction digest work?
Explanation opens after your attempt
Correct Answer
A. बिजली की आपूर्ति बंद करके, उचित सुरक्षा उपकरणों के साथ spill को साफ करेंTurn off the power supply and clean the spill using appropriate safety precautions
Simple Explanation
Gel tank के आसपास buffer गिरने पर तरल पदार्थ विद्युत उपकरणों तक पहुँच सकता है, जिससे झटका लगने या उपकरण को नुकसान होने का जोखिम रहता है। इसलिए पहले बिजली की आपूर्ति बंद करें, फिर संस्थान की सुरक्षा प्रक्रिया के अनुसार दस्ताने जैसे उचित सुरक्षा उपकरणों का उपयोग करके spill साफ करें। वोल्टेज बढ़ाना या कार्य जारी रखना जोखिमपूर्ण है; restriction enzyme spill साफ करने के लिए उपयोग नहीं होता। परीक्षा टिप: विद्युत उपकरण के पास तरल spill हो तो पहला कदम हमेशा power off करना होता है। / A buffer spill around a gel tank can reach electrical parts and create a risk of electric shock or equipment damage. Therefore, first switch off the power supply, then clean the spill using appropriate protective equipment and the laboratory safety procedure. Increasing the voltage or continuing the run is unsafe, and a restriction enzyme is not used to clean a spill. Exam tip: For a liquid spill near electrical equipment, the first action is to turn off the power.

Restriction digestion में UV shield क्यों use किया जाता है?
Why is UV shield used in restriction digestion gel work?
Explanation opens after your attempt
Correct Answer
A. आँखों और त्वचा को हानिकारक UV विकिरण से बचाने के लिएTo protect the eyes and skin from harmful UV radiation
Simple Explanation
UV shield का उपयोग gel work के दौरान UV transilluminator से निकलने वाली हानिकारक UV किरणों से आँखों और त्वचा की सुरक्षा के लिए किया जाता है। DNA fragments को दिखाई देने योग्य बनाने का कार्य सामान्यतः fluorescent dye करता है, UV shield नहीं। परीक्षा टिप: UV transilluminator से जुड़े प्रश्नों में safety goggles, face shield और skin protection याद रखें। / A UV shield is used during gel work to protect the eyes and skin from harmful UV radiation emitted by a UV transilluminator. A fluorescent dye generally makes DNA fragments visible; the UV shield does not perform this function. Exam tip: Associate UV transilluminators with goggles, face shields, and skin protection.

Restriction digestion में sharps safety कब relevant है?
When is sharps safety relevant in restriction digestion?
Explanation opens after your attempt
Correct Answer
A. जेल बैंड काटने के लिए ब्लेड या स्केल्पेल का उपयोग करते समयWhile using a blade or scalpel to cut a gel band
Simple Explanation
जेल से DNA बैंड काटते समय ब्लेड या स्केल्पेल जैसे धारदार उपकरणों का उपयोग हो सकता है, इसलिए कटने की चोट से बचने के लिए sharps safety आवश्यक है। इस्तेमाल किए गए ब्लेड को उचित sharps container में डालना चाहिए। एंजाइम को पिघलाना या DNA की मात्रा मापना सामान्यतः धारदार उपकरणों से जुड़ी प्रक्रिया नहीं है। परीक्षा टिप: जहाँ needle, blade या scalpel हो, वहाँ sharps safety लागू होती है। / Sharps safety is relevant when a blade or scalpel is used to excise a DNA band from a gel, because these tools can cause cut injuries. Used blades should be discarded in an appropriate sharps container. Thawing an enzyme or quantifying DNA does not normally involve a sharp instrument. Exam tip: Think of sharps safety whenever needles, blades, or scalpels are used.
