DNA sings

DNA sings
Why not try and convert your own DNA into music. This is quite easy using software available in most schools. Proteins use up to 20 amino acids to form their sequence, and, of course, DNA uses triplets of four bases Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) to code for these. So, in C major, you give each amino acid a note around middle C. I decided to use the low notes for basic amino acids like lysine and arginine, and high notes for acidic amino acids like aspartic acid and glutamic acid. I then typed these in using Sibelius, that then puts the notes on a stave. You can then play this with any instrument. I used two calcium binding bioluminescent proteins I have studied for forty years. The result is in the picture. Listen to the Wav file. When you hear high notes, this is where the calcium binds. You can then use software like Cubase or Garage band to add an accompaniment.

Have a go, and email us your results. We will put them up on the web site.

Good luck.
