The present invention relates generally to 3′-OH unblocked, labeled and unlabeled nucleotides and nucleosides with 5-methoxy-substituted nitrobenzyl-based photocleavable terminating groups for use in methods and systems related to DNA and RNA sequencing and analysis. These compounds, which may be represented by the following formulas:
wherein the variables are defined herein, may be used as reversible terminators as they exhibit fast nucleotide incorporation kinetics, single-base termination, high nucleotide selectivity, and rapid terminating group cleavage that results in a naturally occurring nucleotide.
