Type II restriction endonucleases
A) require ATP energy to cleave dsDNA.
B) recognize nucleotide sequences that are palindromic.
C) natively function to methylate specific nucleotides and prevent foreign DNA from being incorporated into the genome.
D) are heterodimers.

Question

Quizplus · Accepted Answer

Type II restriction endonucleases recognize nucleotide sequences that are palindromic, meaning they read the same in both directions on the complementary strands of DNA. This allows them to cut both strands of DNA at the same location, creating a blunt or sticky end. They do not require ATP energy to cleave dsDNA and are not typically involved in DNA methylation or prevention of foreign DNA incorporation. They can be homodimers or monomers.
