Abstract:
The present invention provides an improved system for linking nucleic acids to one another. In particular, the present invention provides techniques for producing DNA product molecules that may be easily and directly ligated to recipient molecules. The product molecules need not be cleaved with restriction enzymes in order to undergo such ligation. In preferred embodiments of the invention, the DNA product molecules are produced through iterative DNA synthesis reactions, so that the product molecules are amplified products. The invention further provides methods for directed ligation of product molecules (i. e. , for selective ligation of certain molecules within a collection of molecules), and also for methods of exon shuffling, in which multiple different product molecules are produced in a single ligation reaction. Preferred embodiments of the invention involve ligation of product molecules encoding functional protein domains, particularly domains naturally found in conserved gene families. The inventive DNA manipulation system is readily integrated with other nucleic acid manipulation systems, such as ribozyme-mediated systems, and also is susceptible to automation.

Abstract:
An enzymatic method of making a polynucleotide is provided. The method includes combining a selected nucleotide triphosphate, one or more cations, a template-independent polymerase, and an associated processivity factor in an aqueous reaction medium including a target substrate comprising an initiator sequence and having a 3′ terminal nucleotide attached to a single stranded portion, such that the template-independent polymerase and the associated processivity factor interact with the target substrate under conditions which covalently add one or more of the selected nucleotide triphosphate to the 3′ terminal nucleotide. Also provided are mutant template-independent polymerases having a processivity factor attached thereto.

The present disclosure provides a number of targeted nucleic acid FISSEQ library construction methods. Targeted FISSEQ can exhibit several benefits, such as enhanced sensitivity and/or shorter assay time in the detection, identification, quantification, and/or determining the nucleotide sequence of the target species, relative to “random” or “whole-omic” detection via FISSEQ.
