Susumu Ohno was born to Japanese parents in Keijō, Chōsen (present-day Seoul, South Korea), Empire of Japan on February 1, 1928.
He also discovered in 1956 that the Barr body of mammalian female nuclei was in fact a condensed X chromosome.
[4][5] In 1986, Ohno authored a paper published in Immunogenetics that explored the relationship between DNA genetic sequences and music.
"An enzyme (phosphoglyceratekinase), which breaks down sugar (glucose) in the body revealed itself to Ohno as a lullaby.
``A violinist recorded the tune, and when kindergarten teachers in Tokyo play it, their youngsters yawn and willingly take their naps,``" said Ohno.
