(57) [Abstract] [PROBLEMS] To improve the formation efficiency of an assigning molecule. SOLUTION: (a) A donor region capable of binding to the 3 'end of a nucleic acid, a PEG region containing polyethylene glycol as a main component bound to the donor region, and a peptide bound by a transpeptidation reaction bound to the PEG region. A spacer molecule comprising a peptide acceptor region comprising a group to be obtained, and (b) Contains a 5 'untranslated region containing a transcription promoter and translation enhancer, an ORF region encoding a protein bound to the 3' side of the 5 'untranslated region, and a poly A sequence bound to the 3' side of the ORF region A genotype molecule formed by binding the 3 'end of a coding molecule, which is a nucleic acid containing a 3' end region, to a phenotype molecule, which is a protein encoded by the ORF region in the genotype molecule, in a transpeptidation reaction Mapping molecules. |
