Question 1/5 Easy Biotechnology Processes of Recombinant DNA Technology Cutting of DNA Class 11 Level 54

Restriction mapping में complete digestion क्यों आवश्यक है?

Why is complete digestion necessary in restriction mapping?

Explanation opens after your attempt
Correct Answer

A. क्योंकि partial digestion false fragment pattern दे सकती हैBecause partial digestion can give a false fragment pattern

Step 1

Concept

Incomplete cutting can give extra bands. Accurate band pattern is very important in mapping.

Step 2

Why this answer is correct

The correct answer is A. क्योंकि partial digestion false fragment pattern दे सकती है / Because partial digestion can give a false fragment pattern. Incomplete cutting can give extra bands. Accurate band pattern is very important in mapping.

Step 3

Exam Tip

Incomplete cutting extra bands दे सकता है। Mapping में accurate band pattern बहुत जरूरी है।

Single digest restriction mapping में क्या जानकारी दे सकता है?

What information can a single digest give in restriction mapping?

Explanation opens after your attempt
Correct Answer

D. एक enzyme के cut sites से बने fragment sizesFragment sizes made by one enzyme cut sites

Step 1

Concept

A single digest gives the pattern for one enzyme. Double digests are also useful for a complete map.

Step 2

Why this answer is correct

The correct answer is D. एक enzyme के cut sites से बने fragment sizes / Fragment sizes made by one enzyme cut sites. A single digest gives the pattern for one enzyme. Double digests are also useful for a complete map.

Step 3

Exam Tip

Single digest एक enzyme का pattern देता है। Complete map के लिए double digests भी useful होते हैं।

रैखिक डीएनए में दो प्रतिबंध स्थल हों तो सामान्यतः कितने खंड बनेंगे?

If linear DNA has two restriction sites how many fragments generally form?

Explanation opens after your attempt
Correct Answer

A. तीनThree

Step 1

Concept

Two cuts in linear DNA produce three fragments. For exams remember fragments equal cuts plus one for linear DNA.

Step 2

Why this answer is correct

The correct answer is A. तीन / Three. Two cuts in linear DNA produce three fragments. For exams remember fragments equal cuts plus one for linear DNA.

Step 3

Exam Tip

रैखिक डीएनए में दो कट तीन खंड बनाते हैं। परीक्षा में linear DNA fragments के लिए cuts plus one याद रखें।
