Restriction enzymes recognize specific DNA sequences and cut each strand of DNA at specific locations at the target sequence. The result of digesting a particular genome with a particular restriction enzyme is a collection of restriction fragments of defined length and composition. These can be used to generate restriction maps or create pieces with sticky ends. These sticky ends can be used to attach to other fragments that have sticky ends caused by cutting with a different...

15- Which option BEST describes sticky ends by restriction enzymes B. Sticky ends A. Sticky ends are DNA fragments that carry a higher charge than normal after they have been cleaved are DNA fragments cleaved by a restriction enzyme so that one strand is longer than the other C. Sticky ends are DNA fragments cleaved by a restriction enzyme so that both strands are the same length. D. Sticky ends are DNA fragments that attract a carbohydrate molecule to one...
