A restriction enzyme<span> is an </span>enzyme<span> that cuts DNA after recognizing a specific sequence of DNA. You can think of </span>restriction enzymes<span> as molecular scissors. Scientists can use </span>restriction enzymes<span> to cut a single gene from a larger piece of DNA. </span>Restriction enzymes<span> evolved in bacteria. (please thank me and give me brainliest:))</span>
Restriction enzymes cut the large DNA of human cells into smaller fragments at specific regions called as restriction sites.
Explanation:
Restriction enzymes are endonucleases that cut the DNA into smaller fragments. These DNA fragments are separated from each other through gel electrophoresis and used to make the DNA profiles of individuals. Thus, restriction enzymes help in study of human genome by carrying out site specific digestion of human DNA.
