Sydney Brenner, the Nobel laureate whose studies on the roundworm
Caenorhabditis elegans led to seminal discoveries in genetics and
developmental biology, died in Singapore. He was 92 years old.
Brenner discovered fundamental steps in how cells use DNA to make
the proteins that enable life. He found that sequences of three DNA
bases code for the amino acids that form proteins. And he discovered
that RNA molecules carry that information to ribosomes, the cellular
machines that synthesize proteins.
