The objective of the invention is to provide nucleic acid derivatives with designated compounds introduced specifically into the base of nucleic acids. A DNA or RNA, or a nucleic acid molecular weight marker, wherein a designated compound (R), which is selected from any one of dyes, fluorescent dyes, RI labeled substances, and compounds capable of linking specifically to other compounds, is introduced at the N-3 position of a thymine base or uracil base in which (R') at Position 1 is other than hydrogen atom.
