Card 1मेज़बान-वाहक प्रणाली का परिचय

पुनर्योगज DNA प्रौद्योगिकी में पोषी-वाहक प्रणाली क्या है?

Answer

यह दो घटक प्रणाली है जो एक अनुकूल मेजबान और एक वाहक से बनी है। वाहक वांछित DNA प्रविष्टि को ले जाता है, और मेजबान उस DNA की प्रतिकृति और अभिव्यक्ति के लिए आवश्यक एंजाइम और प्रोटीन प्रदान करता है।…

Card 2Introduction to host-vector system

What is the host–vector system in recombinant DNA technology?

Answer

It is a two-component system made of a compatible host and a vector. The vector carries the desired DNA insert, and the host provides the enzymes and proteins needed for replication and expression of …

Card 3Vector requirement

Why is a vector needed for gene cloning?

Answer

A vector is needed because the desired DNA must enter a host cell and be copied there. The vector also needs an origin of replication, unique restriction sites, and at least one selectable marker so t…

Card 4वेक्टर की आवश्यकता

जीन क्लोनिंग के लिए वेक्टर की आवश्यकता क्यों होती है?

Answer

एक वेक्टर की आवश्यकता होती है क्योंकि वांछित DNA को एक मेजबान कोशिका में प्रवेश करना चाहिए और वहां कॉपी किया जाना चाहिए। वेक्टर को प्रतिकृति के मूल, अद्वितीय प्रतिबंध स्थलों और कम से कम एक चयन योग्य म…

Card 5वेक्टर विशेषताएँ

क्लोनिंग वेक्टर की आवश्यक विशेषताएं क्या हैं?

Answer

क्लोनिंग वेक्टर छोटा होना चाहिए, प्रतिकृति की उत्पत्ति होनी चाहिए, अद्वितीय प्रतिबंध स्थल होने चाहिए, और इसमें कम से कम एक चयन योग्य मार्कर होना चाहिए जैसे कि ampR या tetR। ये विशेषताएं वेक्टर को मेजब…

Card 6Vector features

What are the essential features of a cloning vector?

Answer

A cloning vector should be small, should have an origin of replication, should contain unique restriction sites, and should have at least one selectable marker such as ampR or tetR. These features hel…

Card 7Plasmids

Define plasmids.

Answer

Plasmids are circular, double-stranded, extra-chromosomal DNA molecules capable of autonomous replication. They occur naturally in bacteria and also in some eukaryotes such as yeast.

Card 8प्लास्मिड

प्लाज्मिड की परिभाषा दीजिए।

Answer

प्लास्मिड (plasmids) वृत्ताकार, द्वि-रज्जुक, अतिरिक्त-गुणसूत्र DNA अणु होते हैं जो स्वायत्त प्रतिकृति करने में सक्षम होते हैं। ये प्राकृतिक रूप से बैक्टीरिया में और कुछ यूकेरियोट्स जैसे कि खमीर में भी…
