The function of Restriction II enzyme after binding to a unique recognition site is which of the following?
Type II restriction endonucleases recognize and bind specifically to a unique recognition site that is typically a 4-, 6-, or 8-bp palindrome. After binding they introduce a double-stranded cut at the sequence. Restriction cleavage occurs at one site producing "blunt ends" or, if it occurs in a staggered fashion, "overhanging ends".
