核酸配列:A ATG C ATG TT ATG G ATG CCC ATG AAA ATG AA
第二の設定方式は、表2および表3に示すように、特定の塩基(配列単位)を配列組み合わせの開始および/または終了マーカーとして使用し、残りの塩基の一つまたは二つ以上の繰り返し連結回数または任意の組み合わせに基づいて順次的な情報単位を設定する方式である。
核酸配列:AT AAAAT CCCT CCCCCT CT AAAT AAT
また、表3に示すように、Aが配列組み合わせの開始マーカーであって、A、T、C、Gの二つの組み合わせが配列組み合わせとしてそれぞれ設定されている。前記「1480632」の情報データを前記表3の方式で暗号化すると、次のとおりである。
核酸配列:ACC ATC AGT AAA ATG ACG ACT
第三の設定方式は、表4に示すように、特定の塩基の二つまたは三つ以上の配列組み合わせにそれぞれ特定の情報単位を設定し、これらの特定の組み合わせによって価値情報を設定する方式である。
核酸配列:ATA TTC TTT CAA CAC ATC ATC TAT TAT CCC
本発明の人為的核酸配列は、前で例示した配列組み合わせと情報単位との対応方式の中からいずれかを選択して使用される。しかし、前述した方式は、数多くの配列組み合わせと情報単位とを対応させる方式の一部に過ぎない。
