No
Study Notes
Restriction Enzymes and DNA Segments
- Okazaki fragments are the single-stranded DNA segments created by some Restriction Enzymes (REs).
DNA Joining Process
- The process by which DNA molecules with complementary sticky ends are joined is called ligation.
Types of Ends
- Blunt ends are the types of ends left by some REs that can be re-ligated together with any other blunt-ended piece of DNA using DNA ligase.
DNA Ligase
- DNA ligase is the enzyme used to reseal DNA molecules with complementary sticky ends.
Blunt-Ended DNA
- DNA molecules with blunt ends cannot be joined by complementary base pairing, but instead, require DNA ligase for resealing.
