Oligoribonucleotide- and ribozyme-analoguer with terminal 3',3'- and 5',5'-bonds respectively

THE INVENTION REFERS TO THE ANALOGUE OF OLIGORRIBONUCLEOTIDES ANALOGS WITH LIGATURES 3 '' - 3 '' TERMINALS. THIS MODIFICATION STABILIZES THE MOLECULES SO MODIFIED, INCLUDING ALSO THE RIBOZIMA, WITHOUT THEIR PROPERTIES CHANGING IN A DISADVANTAGING WAY, EVENTUALLY INCLUDING CATALYTIC ACTIVITIES.
