DEFINITION

Classification: 435/91.3

Polynucleotide contains only ribonucleotide monomers:

(under subclass 91.1) Processes wherein the product synthesized is (see image below): where "n" is a whole number greater than 2 and R is purine or pyrimidine or a substituted purine or pyrimidine. [figure]

(1) Note. The two purines, adenine and guanine, and the two pyrimidines, cytosine and uracil, are used in ribonucleic acid (RNA) synthesis.
