Modular nucleotide compositions and uses therefor
First Claim
1. A composition comprising a reaction component coupled to a fluorescent label through a non-covalent linkage component configured to provide a separation between the fluorescent label and the reaction component, wherein the reaction component comprises a nucleoside polyphosphate, and further wherein the fluorescent label causes photo-induced damage to an enzyme interacting with the reaction component under excitation illumination in the absence of the separation provided by the non-covalent linkage component, which shields the enzyme from the fluorescent label during interaction between the enzyme and the reaction component.

Abstract
Nucleic acid compositions, methods of making and using such compositions that comprise modular functional groups that can be configured to provide desired functionality to different nucleotide types, through a swappable and preferably non-covalent linkage component. Such compositions are useful in a variety of applications including nucleic acid analyses.
