See them allWhat is recombinant DNA technology?
Answer
Recombinant DNA technology, also called genetic engineering, means the direct manipulation of the nucleic acid or genome of an organism. It is used to alter genetic material for useful purposes in med…
पुनर्योजी DNA तकनीक क्या है?
Answer
पुनर्योगज DNA तकनीक (recombinant ⟧ 0 technology) या आनुवंशिक अभियान्त्रिकी (genetic engineering) का अर्थ है किसी जीव के न्यूक्लिक अम्ल या जीनोम का प्रत्यक्ष हेरफेर। इसका उपयोग चिकित्सा, कृषि और अनुसंध…
जीव विज्ञान में बड़ी प्रगति के बाद ही पुनः संयोजक DNA तकनीक क्यों संभव हुई?
Answer
यह जैव रसायन, आनुवंशिकी, कोशिका विज्ञान, सूक्ष्म जीव विज्ञान और आणविक जीव विज्ञान में प्रगति के बाद संभव हो पाया। महत्वपूर्ण कदमों में DNA संरचना, आनुवंशिकता में इसकी भूमिका को समझना और DNA को अलग करन…
Why was recombinant DNA technology possible only after major progress in biology?
Answer
It became possible after progress in biochemistry, genetics, cytology, microbiology, and molecular biology. Important steps included understanding DNA structure, its role in heredity, and developing m…
What is the role of DNA in heredity and biotechnology?
Answer
DNA carries genetic information and also passes it from one generation to the next. This understanding made it possible to think about changing DNA directly to obtain useful products and traits.
वंशानुक्रम और जैव प्रौद्योगिकी में DNA की क्या भूमिका है?
Answer
DNA आनुवंशिक जानकारी ले जाता है और इसे एक पीढ़ी से दूसरी पीढ़ी में भी पहुंचाता है। इस समझ ने उपयोगी उत्पादों और लक्षणों को प्राप्त करने के लिए DNA को सीधे बदलने के बारे में सोचना संभव बना दिया।…
प्रतिबंध एंजाइम क्या हैं?
Answer
प्रतिबंधन एंजाइम (Restriction enzymes) वे एंजाइम होते हैं जो DNA के अणुओं को काटने के लिए कैंची की तरह काम करते हैं। वे पुनर्संयोजित DNA प्रौद्योगिकी में आवश्यक हैं क्योंकि वे DNA को विशिष्ट स्थानों प…
What are restriction enzymes?
Answer
Restriction enzymes are enzymes that act as scissors to cut molecules of DNA. They are essential in recombinant DNA technology because they allow precise cutting of DNA at specific places.
