| 1. | These cations facilitate the base pairing of the ribozyme with the substrate.
|
| 2. | 5-BrU exists in three tautomeric forms that have different base pairing properties.
|
| 3. | There was another near-discovery of the base pairing rules in early 1952.
|
| 4. | Base pairing in RNA occurs when RNA folds between complementarity regions.
|
| 5. | This is shown by the high conservation of base pairings across diverse species.
|
| 6. | However, it has less base pairing in the upper stem than DHBV epsilon.
|
| 7. | The asymmetric metal base pairing system is orthogonal to the Watson-Crick base pairs.
|
| 8. | In Watson-Crick base pairing, it forms three hydrogen bonds with guanine.
|
| 9. | These hydrogen bonding modes are for classical Watson Crick base pairing.
|
| 10. | The glycol unit has just three carbon atoms and still shows Watson-Crick base pairing.
