<P>PROBLEM TO BE SOLVED: To provide more than one prokaryotic cells having various populations of oligonucleotide expressibly combined to an element of expression, and the expressible nucleotide has a requested bias of random codon sequence. <P>SOLUTION: The composition is a composition of substances containing more than one cells containing various populations of oligonucleotide expressibly combined to the element of expression, and the expressible oligonucleotide has the codon sequence with requested bias produced by random linking of populations of a first and a second oligonucleotide precursors having sequences of random codons with the requested bias. <P>COPYRIGHT: (C)2004,JPO |
