Abstract

According to one embodiment, a nucleic acid condensing peptide includes one terminal having a first sequence RRRRRR and another terminal having a second sequence RQRQR. Between the first sequence and the second sequence, none or one or more intermediate sequences each consisting of RRRRRR or RQRQR are included. Further, of the first sequence, the second sequence and the intermediate sequences, two or more neutral amino acids are included between any two sequences adjacent to each other.
