Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

Methods for the synthesis of polynucleotides using polymerases nucleotide analogs with labile terminator groups that allow stepwise addition of nucleotides are described. These nucleotide analogs may have a modification on 3′, 2′, or 3′-2′-bridged hydroxyl groups or on nucleobase moieties and can be used in the synthesis of natural or modified polynucleotides suitable for use in biological systems. The labile terminator groups are removed under mild conditions or by enzymes. They are accepted as substrates by polymerases. The synthesis may be carried out on a surface.
