| abstract |
A nucleic acid array is provided that can efficiently perform analysis, and further, can estimate the number of expressions of amino acid mutations for all cases by use of a smaller number of arrays. The nucleic acid array has a plurality of oligonucleotides immobilized on a substrate, wherein the oligonucleotide has a sequence site that forms base pairs with at least two bases of the four bases (A, T, C, G or U) or has a sequence site that does not form a base pair with any of the four bases. |
