Question

Why would different restriction enzymes cut the same DNA molecule into different numbers of fragments

Answer 1

Because different restriction sites are used by different restriction enzymes to cleave DNA.

What is restriction sites?

• A restriction site is a segment of DNA with a base pair count between 6 and 8 that binds to a certain restriction enzyme. There are numerous restriction enzymes that have been identified from bacteria. By cleaving the viral DNA, they naturally render invasive viruses inactive.
• Restriction enzymes are beneficial in a variety of contexts. Each organism has a unique DNA sequence, so each one will have a unique arrangement of restriction sites.
