| The vesicles were immobilized on supported bilayers and single-molecule analysis was performed for DNA molecules and hairpin ribozymes. |
| This view has been strengthened by the discovery that some forms of RNA, called ribozymes, can act like non-protein enzymes to catalyze biological reactions. |
| We therefore encapsulated hairpin ribozymes inside 200-nm vesicles to test for surface effects. |
| They can act as real enzymes and, by analogy to protein enzymes, are called ribozymes. |
| Gene therapy is also making use of catalytic RNA through the construction of ribozymes. |
| They placed the DNA copy between two ribozymes, RNA molecules that have enzymatic function and can cleave RNA sequence at specific locations. |
