Abstract
Method for analyzing a nucleic acid molecule, without fragmenting the molecule, by vaporizing a mixture of the molecule and a matrix by illuminating the mixture with visible laser light absorbed by the matrix and not by the nucleic acid molecule. The method is useful for determining the nucleotide sequence of a polynucleotide by using mass spectrometry to determine the molecular weights of individual single-stranded nucleic acid molecules in a population including a plurality of single-stranded nucleic acid molecules generated from the polynucleotide, each molecule having a different molecular weight, and one defined terminus and one variable terminus which terminates at a specific nucleotide.
