What will happen if the target DNA also possesses the same Restriction Site as the adaptors?
What will happen if the target DNA also possesses the same Restriction Site as the adaptors?
- The adaptors will produce new DNA with modified ends
- The adaptors will not be able to bind to the target DNA
- The adaptors will bind only to the target DNA
- The adaptors' sticky ends will bind with each other (correct)
Why is DNA ligase unable to form a phosphodiester bridge between the 5-OH and 3-OH ends of adaptors?
Why is DNA ligase unable to form a phosphodiester bridge between the 5-OH and 3-OH ends of adaptors?
- The adaptors cannot bind to DNA molecules
- The adaptors lack phosphate groups (correct)
- The adaptors' ends are not complementary
- The adaptors have abnormal termini
