DEFINITION

Classification: 536/23.1

DNA or RNA fragments or modified forms thereof (e.g., genes, etc.):

(under subclass 22.1) Compounds which are fragments of nucleic acid having a specific sequence of deoxyribonucleotide units, or ribonucleotide units, linked by successive 3i-5i phosphodiester linkages, or modified derivatives thereof.

(1) Note. A gene is a fragment of DNA that encodes a specific polypeptide in a recombinant process.

(2) Note. "Encodes" means that the fragment of DNA specifies the amino acid sequence of the polypeptide expressed by a microorganism that has been transformed with such fragment of DNA.

(3) Note. For purposes of this class the term microorganism includes bacteria, actinomycetales, cyanobacteria (unicellular algae), fungi, protozoa, animal cells, plant cells, and virus.
