In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
Restriction enzymes are used to cut a double stranded DNA at specific recognition sites.Then these pieces of DNA strand,carrying a particular information,are incorporated in a foreign body using vectors.
