DEFINITION

Classification: 435/91.1

Polynucleotide (e.g., nucleic acid, oligonucleotide, etc.):

(under subclass 89) Processes wherein the product synthesized is (see image below) where "n" is a whole number greater than 2, R' is H or OH, and R is purine or pyrimidine or a substituted purine or pyrimidine. [figure]

(1) Note. The two purines, adenine and guanine, are found in both deoxyribonucleic acid (DNA) and ribonucleic acid

(RNA). The pyrimidine cytosine is found in both DNA and RNA while the pyrimidine thymine is found only in DNA and the pyrimidine uracil appears only in RNA.

(2) Note. This and the indented subclasses are intended to include processes wherein the polynucleotide synthesized did not exist as such in the starting material. The synthesized material may be entirely different from the starting material, or it may have a substituted, deleted, or added nucleotide or nucleotides.

(3) Note. Substituted purine or pyrimidine includes only those derivatives which are substituted on, rather than in the respective ring positions.

(4) Note. If the disclosure is unclear as to what kind of polynucleotide is being made (i.e., RNA or DNA) the subject matter should be classified in the first appearing appropriate subclass for either RNA or DNA and cross-referenced to other appropriate subclasses for RNA or DNA. Unless the subject matter is directed to an acellular amplification process, synthesis of RNA is intended for subclasses 91.3+.
