Antibiotic selection से पहले recovery क्यों दी जाती है?

Why is recovery given before antibiotic selection?

Explanation opens after your attempt
Correct Answer

A. Resistance marker express होने का समय देने के लिएTo give time for resistance marker expression

Step 1

Concept

Cells need time to make resistance protein. Immediate antibiotic exposure can reduce survival.

Step 2

Why this answer is correct

The correct answer is A. Resistance marker express होने का समय देने के लिए / To give time for resistance marker expression. Cells need time to make resistance protein. Immediate antibiotic exposure can reduce survival.

Step 3

Exam Tip

Cells को resistance protein बनाने का समय चाहिए। Immediate antibiotic exposure survival घटा सकता है।

सक्षम होस्ट में प्लास्मिड प्रवेश कराने के बाद पहला selection संकेत क्या हो सकता है?

What can be the first selection signal after plasmid entry into a competent host?

Explanation opens after your attempt
Correct Answer

A. एंटीबायोटिक plate पर colony growthColony growth on antibiotic plate

Step 1

Concept

Growth on an antibiotic plate gives an initial sign of a resistance marker. Separate screening is needed for insert confirmation.

Step 2

Why this answer is correct

The correct answer is A. एंटीबायोटिक plate पर colony growth / Colony growth on antibiotic plate. Growth on an antibiotic plate gives an initial sign of a resistance marker. Separate screening is needed for insert confirmation.

Step 3

Exam Tip

Antibiotic plate पर growth resistance marker का शुरुआती संकेत देती है। Insert confirmation के लिए अलग screening चाहिए।

एंटीबायोटिक प्लेट पर transformed bacteria क्यों बढ़ सकते हैं?

Why can transformed bacteria grow on an antibiotic plate?

Explanation opens after your attempt
Correct Answer

B. क्योंकि उनमें resistance marker वाला plasmid हो सकता हैBecause they may have a plasmid with a resistance marker

Step 1

Concept

A resistance marker lets bacteria survive on the related antibiotic. This selects transformed cells.

Step 2

Why this answer is correct

The correct answer is B. क्योंकि उनमें resistance marker वाला plasmid हो सकता है / Because they may have a plasmid with a resistance marker. A resistance marker lets bacteria survive on the related antibiotic. This selects transformed cells.

Step 3

Exam Tip

Resistance marker बैक्टीरिया को संबंधित एंटीबायोटिक पर जीवित रहने देता है। इससे transformed cells चुनी जाती हैं।

कौन सा option cloning vector selection में antibiotic का सही role है?

Which option gives the correct role of antibiotic in cloning vector selection?

Explanation opens after your attempt
Correct Answer

A. Marker वाले cells को चुनने में मददHelps select cells with marker

Step 1

Concept

Antibiotic allows only cells with resistance marker to grow. This enables selection.

Step 2

Why this answer is correct

The correct answer is A. Marker वाले cells को चुनने में मदद / Helps select cells with marker. Antibiotic allows only cells with resistance marker to grow. This enables selection.

Step 3

Exam Tip

Antibiotic केवल उन cells को बढ़ने देता है जिनमें resistance marker होता है। इससे selection संभव होती है।

यदि only antibiotic selection की जाए तो कौन सी जानकारी missing रह सकती है?

If only antibiotic selection is done what information may remain missing?

Explanation opens after your attempt
Correct Answer

A. Insert सही जुड़ा है या नहींWhether insert is correctly joined

Step 1

Concept

Antibiotic selection shows vector presence. Screening or sequencing is needed for insert confirmation.

Step 2

Why this answer is correct

The correct answer is A. Insert सही जुड़ा है या नहीं / Whether insert is correctly joined. Antibiotic selection shows vector presence. Screening or sequencing is needed for insert confirmation.

Step 3

Exam Tip

Antibiotic selection vector presence दिखाती है। Insert confirmation के लिए screening या sequencing चाहिए।

एक host cell vector नहीं लेती। Antibiotic plate पर क्या होगा?

A host cell does not take the vector. What will happen on an antibiotic plate?

Explanation opens after your attempt
Correct Answer

A. Resistance marker न होने से growth नहीं होगीIt will not grow because it lacks resistance marker

Step 1

Concept

A non-transformed cell lacks the resistance marker. Therefore it cannot grow on an antibiotic plate.

Step 2

Why this answer is correct

The correct answer is A. Resistance marker न होने से growth नहीं होगी / It will not grow because it lacks resistance marker. A non-transformed cell lacks the resistance marker. Therefore it cannot grow on an antibiotic plate.

Step 3

Exam Tip

Non-transformed cell में resistance marker नहीं होता। इसलिए antibiotic plate पर वह बढ़ नहीं सकती।

एंटीबायोटिक plate पर colony बढ़ी लेकिन insert confirm नहीं हुआ। क्या जरूरत है?

A colony grew on an antibiotic plate but insert is not confirmed. What is needed?

Explanation opens after your attempt
Correct Answer

A. Further screening या confirmationFurther screening or confirmation

Step 1

Concept

Antibiotic growth shows vector uptake. Screening or analysis may be needed to confirm the insert.

Step 2

Why this answer is correct

The correct answer is A. Further screening या confirmation / Further screening or confirmation. Antibiotic growth shows vector uptake. Screening or analysis may be needed to confirm the insert.

Step 3

Exam Tip

Antibiotic growth vector uptake दिखाता है। Insert की पुष्टि के लिए screening या analysis जरूरी हो सकता है।

कौन सा चयन केवल vector लेने वाली कोशिका बताता है लेकिन insert की पुष्टि नहीं करता?

Which selection shows cells that took vector but does not confirm insert presence?

Explanation opens after your attempt
Correct Answer

A. एंटीबायोटिक चयनAntibiotic selection

Step 1

Concept

Antibiotic selection chooses vector-containing cells. Screening or confirmation tells whether insert is present.
