Restriction fragment

A **restriction fragment** is a specific DNA segment that results from the action of restriction enzymes, which are proteins that cut DNA at specific sequences. When DNA is digested by these enzymes, it is broken down into smaller pieces, each of which is referred to as a restriction fragment. The main characteristics of restriction fragments include: 1. **Length**: The length of restriction fragments can vary widely, depending on the location of the cut sites in the DNA and the specific restriction enzyme used.
