Triplet Code vs others
Country: United States
Date: January 2009
How do scientists know that the genetic code is based
on triplet codons (three bases for every amino acid)? Why can't it
be just two bases?
There are thousands of experiments that support the triplet code theory,
but the most obvious evidence against the doublet code is that you can
only code for 4 x 4 =16 different codons but there are 20 different
amino acids that must be coded for.
