Almost every messenger RNA contains a natural long «tail» — a strand of hundreds
of adenosine bases located on one end.

Pugh added that it was easy to dismiss these fragments because they lacked a feature called polyadenylation — a long string
of genetic material,
adenosine bases — that protect the RNA from being destroyed.
That
base, an
adenosine, is conserved in organisms throughout the tree
of life, he reports, and it could well date back to the RNA world.
Working with French composer Richard Krüll, the pair turned the complete nucleotide sequences
of several microbe genes into compositions
based on DNA
bases: A (
adenosine), C (cytosine), G (guanine), and Thymine (which they have translated to «Re,» or D).
