Study Notes
- Capital letters represent bases and ' indicates the complementary base.
- Restriction enzymes break DNA at specific recognition sequences.
- Breaks can be staggered or blunt.
- Staggered breaks form cohesive ends with single-stranded extensions.
- Blunt ends cannot circularize spontaneously.
- Each restriction enzyme generates a unique set of fragments.
- Hundreds of restriction enzymes have been characterized.
- Most attack short palindromic target sequences.
- Some recognize other types of specific sequences.
- Werner Arber, Hamilton Smith, and Daniel Nathans were awarded the 1978 Nobel Prize for recognizing the usefulness of restriction enzymes.
