1. A method of detecting a fluorescently labeled nucleotide incorporated into a DNA coupled to a phosphine moiety, comprising:
- a) reacting a DNA comprising an azido group with a compound comprising a phosphine moiety to produce the DNA coupled to the phosphine moiety;
b) contacting the DNA coupled to the phosphine moiety of step a) with a polymerase and a fluorescently labeled nucleotide so as to incorporate the fluorescently labeled nucleotide into the DNA coupled to the phosphine moiety; and
c) detecting the fluorescently labeled nucleotide incorporated into the DNA coupled to the phosphine moiety.

Abstract
This invention provides methods for attaching a nucleic acid to a solid surface and for sequencing nucleic acid by detecting the identity of each nucleotide analogue after the nucleotide analogue is incorporated into a growing strand of DNA in a polymerase reaction. The invention also provides nucleotide analogues which comprise unique labels attached to the nucleotide analogue through a cleavable linker, and a cleavable chemical group to cap the —OH group at the 3′-position of the deoxyribose.
