DEFINITION

Classification: 536/27.11

Preparing by cleaving nucleic acids or by attaching an N-heterocyclic base to a sugar ring:

(under subclass 27.1) Processes for the preparation of N-hetero glycosides which include cleaving (degradation) of nucleic acids or bonding an N-heterocyclic base to a sugar ring.

(1) Note. Chemical cleaving (degradation) of nucleic acids

is provided for in this subclass.
