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

Question

Quizplus · Accepted Answer

Type II restriction endonucleases recognize nucleotide sequences that are palindromic, meaning the sequence reads the same on both strands in opposite directions. This allows them to cleave both strands of the DNA at the same position, creating a blunt or sticky end. They do not require ATP energy to cleave dsDNA.
