Summary Introduction

To describe:

The term restriction enzymes.

Introduction:

Restriction enzymes are also known as molecular scissors. These cut the DNA (deoxyribonucleic acid) fragments at recognition sites and produce restriction fragments. Restriction enzymes or endonucleases were discovered by Arber, Nathans, and Smith. Some of the examples of restriction enzymes are Hind III (Haemophilus influenza, strain Rd, discovery order-III), BamHI (Bacillus amyloliquefaciens, strain H, discovery order-I), Hpa I (Haemophilus parainfluenzae, discovery order-I), and Sma I (Serratia marcescens, discovery order-I).
