Linear DNA में cut sites की संख्या और fragments की संख्या का सामान्य संबंध क्या है?

What is the general relation between number of cut sites and fragments in linear DNA?

Explanation opens after your attempt
Correct Answer

B. fragments सामान्यतः cut sites plus oneFragments generally equal cut sites plus one

Step 1

Concept

Each internal cut increases fragment count in linear DNA. Therefore one cut gives two fragments.

Step 2

Why this answer is correct

The correct answer is B. fragments सामान्यतः cut sites plus one / Fragments generally equal cut sites plus one. Each internal cut increases fragment count in linear DNA. Therefore one cut gives two fragments.

Step 3

Exam Tip

Linear DNA में हर internal cut fragment count बढ़ाता है। इसलिए one cut से two fragments बनते हैं।
