The genetic code sees off rivals
There are many possible three-letter
genetic codes that could adequately
encode protein sequences, but what
about the need to encode higher-
order information on binding and
splicing sites? New research shows
that the actual genetic code is better
than potential alternatives at encod-
ing such information at the same
time as encoding protein.
The main function of coding
regions is to specify the amino-acid
sequence. However, these regions
also need to include other elements
-- sequences for splicing out introns
