Abstract: The invention provides improved methods for synthesizing polynucleotides, such as DNA and RNA, using renewable initiators coupled to a solid support. Using the methods of the invention, specific sequences of polynucleotides can be synthesized de novo, base by base, in an aqueous environment, without the use of a nucleic acid template.

Abstract: Provided herein are methods for ligation of polynucleotides containing modified ligation components, particularly modified ligase cofactors, modified acceptors and modified donors. The methods readily applied to ligation-based assays for detection of a nucleic acid sequence where the use of the modified cofactor improves discrimination between matched and mismatched templates. Furthermore, the use of the modified ligation components reduces or eliminates the ligation in the absence of nucleic acid template. In addition, methods are applied to the preparation of nucleic acid libraries using modified acceptor probes and modified donor probes that reduce or eliminate probe dimerization during the ligation process.
