Question 2/10 Easy Biotechnology Processes of Recombinant DNA Technology Cutting of DNA Class 11 Level 52

Partial digestion gel पर कैसे दिख सकती है?

How can partial digestion appear on gel?

Explanation opens after your attempt
Correct Answer

A. expected bands के साथ uncut या larger intermediate bandsUncut or larger intermediate bands with expected bands

Step 1

Concept

In partial digestion some molecules are not fully cut. Therefore intermediate bands can appear.

Step 2

Why this answer is correct

The correct answer is A. expected bands के साथ uncut या larger intermediate bands / Uncut or larger intermediate bands with expected bands. In partial digestion some molecules are not fully cut. Therefore intermediate bands can appear.

Step 3

Exam Tip

Partial digestion में कुछ molecules fully cut नहीं होते। इसलिए intermediate bands आ सकते हैं।

Question 6/10 Easy Biotechnology Principles of Biotechnology Restriction Enzymes Class 11 Level 17

restriction site absent होने पर gel में क्या दिख सकता है?

What may be seen in a gel if the restriction site is absent?

Explanation opens after your attempt
Correct Answer

A. uncut DNA band

Step 1

Concept

If the site is absent the enzyme will not cut. Therefore the original uncut DNA band may appear.

Step 2

Why this answer is correct

The correct answer is A. uncut DNA band. If the site is absent the enzyme will not cut. Therefore the original uncut DNA band may appear.

Step 3

Exam Tip

Site absent होने पर enzyme cut नहीं करेगा। इसलिए original uncut DNA band दिख सकता है।
