DEFINITION

Classification: 514/44

Polynucleotide (e.g., RNA, DNA, etc.):

(under subclass 43) Subject matter which has the following structure, illustrated below, wherein n is a whole number

equal or greater than two, R' is H or OH and R" is purine or pyrimidine or a substituted purine or pyrimidine. [figure]

(1) Note. Substituted pyrimidine or purine includes only those derivatives which are substituted on rather than in the respective ring position, i.e., illustrated below, is present in the structure. The internal ring bonding may be altered by tautomerism or by the addition of substituents without excluding a compound from this subclass. [figure] [caption]Or [figure]
