Solution
The correct option is B Cutting double-stranded DNA
A restriction enzyme is an enzyme that cuts double-stranded DNA at or near specific recognition nucleotide sequences known as restriction sites. To cut DNA, all restriction enzymes make two incisions, once through each sugar-phosphate backbone (i.e., each strand) of the DNA double helix.
