Where, then, is any particular gene--say, the gene for long legs in humans? This is a little like asking where is Beethoven's Piano Sonata in E minor. Is it in the original handwritten score? The printed sheet music? Any one performance--or perhaps the sum of all performances, historical and potential, real and imagined? The quavers and crotchets inked on paper are not the music. Music is not a series of pressure waves sounding through the air; nor grooves etched in vinyl or pits burned in CDs; nor even the neuronal symphonies stirred up in the brain of the listener. The music is the information. Likewise, the base pairs of DNA are not genes. They encode genes. Genes themselves are made of bits.
