What enzyme cuts DNA at a specific sequence of nucleotides?

Explanation:
Restriction enzymes are the proteins that cut DNA when they find their exact recognition sequence. They bind to a short, specific sequence—often a palindrome—and then cleave the backbone at a defined location within or just next to that sequence. This precise cutting allows predictable fragment generation, producing either blunt ends or sticky ends that are useful for cloning and DNA analysis. Other enzymes have different roles: ligase seals breaks in DNA, polymerase synthesizes new DNA strands, and helicase unwinds the double helix.
