A DNA sequence recognized and cleaved by a restriction endonuclease. Restriction sites are often 4 to 6 bp, but some sites are 8 bp or longer. The presence or absence of specific nucleotide modifications (e.g. methylation) determines whether the restriction endonuclease cleaves at its cognate restriction site.
The specific nucleotide sequence in DNA that is recognized by a type II restriction endonuclease and within which it makes a double-stranded cut. Restriction sites usually comprise four or six base pairs that typically are palindromic (q.v.), e.g., 5´GGCC3´ 3´CCGG5´ The two strands may be cut either opposite to one another, to create blunt ends, or in a staggered manner, giving sticky ends, depending on the enzyme involved. See restriction endonuclease.
