अगर no-antibiotic plate पर growth है लेकिन selection plate पर नहीं तो क्या संभव है?

If there is growth on no-antibiotic plate but not on selection plate what is possible?

Explanation opens after your attempt
Correct Answer

A. Cells alive हैं पर plasmid marker selection नहीं हुआCells are alive but plasmid marker selection did not occur

Step 1

Concept

No-antibiotic growth shows viability. Selection plate failure can indicate transformation or marker issue.

Step 2

Why this answer is correct

The correct answer is A. Cells alive हैं पर plasmid marker selection नहीं हुआ / Cells are alive but plasmid marker selection did not occur. No-antibiotic growth shows viability. Selection plate failure can indicate transformation or marker issue.

Step 3

Exam Tip

No-antibiotic growth viability दिखाती है। Selection plate failure transformation या marker issue दिखा सकता है।

Competence और viability में सही संबंध क्या है?

What is the correct relation between competence and viability?

Explanation opens after your attempt
Correct Answer

A. Cells DNA लें और survive भी करेंCells should take DNA and also survive

Step 1

Concept

DNA uptake alone is not enough. Transformed cells should also grow.

Step 2

Why this answer is correct

The correct answer is A. Cells DNA लें और survive भी करें / Cells should take DNA and also survive. DNA uptake alone is not enough. Transformed cells should also grow.

Step 3

Exam Tip

केवल DNA uptake काफी नहीं है। Transformed cells को grow भी करना चाहिए।

Viability कम होने पर transformation result कैसे प्रभावित होगा?

How will transformation result be affected if viability is low?

Explanation opens after your attempt
Correct Answer

A. Colonies कम मिल सकती हैंFewer colonies may be obtained

Step 1

Concept

Dead or weak cells do not form colonies. Therefore viability is necessary for transformation success.

Step 2

Why this answer is correct

The correct answer is A. Colonies कम मिल सकती हैं / Fewer colonies may be obtained. Dead or weak cells do not form colonies. Therefore viability is necessary for transformation success.

Step 3

Exam Tip

Dead या weak cells colonies नहीं बनातीं। इसलिए viability transformation success के लिए जरूरी है।

Competent host की सबसे important practical quality क्या है?

What is the most important practical quality of a competent host?

Explanation opens after your attempt
Correct Answer

A. High viability और DNA uptake abilityHigh viability and DNA uptake ability

Step 1

Concept

A competent host should stay alive and take external DNA. Both viability and competence are needed.

Step 2

Why this answer is correct

The correct answer is A. High viability और DNA uptake ability / High viability and DNA uptake ability. A competent host should stay alive and take external DNA. Both viability and competence are needed.

Step 3

Exam Tip

Competent host को जीवित रहकर external DNA लेना चाहिए। Viability और competence दोनों जरूरी हैं।

Overgrown culture से competent cells बनाने पर क्या risk है?

What is the risk of making competent cells from an overgrown culture?

Explanation opens after your attempt
Correct Answer

A. Transformation efficiency कम हो सकती हैTransformation efficiency may decrease

Step 1

Concept

Cells in an overgrown culture can be less healthy. This can affect both competence and viability.

Step 2

Why this answer is correct

The correct answer is A. Transformation efficiency कम हो सकती है / Transformation efficiency may decrease. Cells in an overgrown culture can be less healthy. This can affect both competence and viability.

Step 3

Exam Tip

Overgrown culture में cells less healthy हो सकती हैं। इससे competence और viability दोनों प्रभावित हो सकते हैं।

Competent cells को बार-बार freeze-thaw करने से क्या हो सकता है?

What can happen if competent cells are repeatedly frozen and thawed?

Explanation opens after your attempt
Correct Answer

A. Competence और viability घट सकती हैCompetence and viability may decrease

Step 1

Concept

Repeated freeze-thaw can damage competent cells. Using aliquots is better.

Step 2

Why this answer is correct

The correct answer is A. Competence और viability घट सकती है / Competence and viability may decrease. Repeated freeze-thaw can damage competent cells. Using aliquots is better.

Step 3

Exam Tip

Repeated freeze-thaw competent cells को damage कर सकता है। Aliquots बनाकर use करना बेहतर है।

Competent cells को gently handle क्यों करना चाहिए?

Why should competent cells be handled gently?

Explanation opens after your attempt
Correct Answer

A. वे fragile हो सकती हैं और viability घट सकती हैThey can be fragile and viability may decrease

Step 1

Concept

Competent cells are sensitive. Harsh mixing or heat can reduce cell survival and competence.

Step 2

Why this answer is correct

The correct answer is A. वे fragile हो सकती हैं और viability घट सकती है / They can be fragile and viability may decrease. Competent cells are sensitive. Harsh mixing or heat can reduce cell survival and competence.

Step 3

Exam Tip

Competent cells sensitive होती हैं। Harsh mixing या heat से cell survival और competence घट सकती है।

Competent cells की viability का अर्थ क्या है?

What does viability of competent cells mean?

Explanation opens after your attempt
Correct Answer

D. Cells जीवित और growth capable हैंCells are alive and capable of growth

Step 1

Concept

Viability means cells are alive and can grow after transformation. Dead cells do not form colonies.

Step 2

Why this answer is correct

The correct answer is D. Cells जीवित और growth capable हैं / Cells are alive and capable of growth. Viability means cells are alive and can grow after transformation. Dead cells do not form colonies.

Step 3

Exam Tip

Viability बताती है कि cells जीवित हैं और transformation के बाद बढ़ सकती हैं। मृत cells colonies नहीं बनातीं।

सक्षम कोशिकाओं को अक्सर ठंडा क्यों रखा जाता है?

Why are competent cells often kept cold?

Explanation opens after your attempt
Correct Answer

B. competence और viability बनाए रखने के लिएTo maintain competence and viability

Step 1

Concept

Competent cells are sensitive and remain stable in cold. Wrong temperature can reduce their ability.

Step 2

Why this answer is correct

The correct answer is B. competence और viability बनाए रखने के लिए / To maintain competence and viability. Competent cells are sensitive and remain stable in cold. Wrong temperature can reduce their ability.

Step 3

Exam Tip

सक्षम कोशिकाएँ संवेदनशील होती हैं और ठंड में स्थिर रहती हैं। गलत तापमान उनकी क्षमता घटा सकता है।
