There are only types of nitrogen

Considering one nucleotide (a :1
coding) it would impossible to codify
amino acids.

Considering nucleotides there would

each triplet of -containing

in the RNA ,
sequential amino acids by them
are together to make
chains. For example, UUU sequence
codifies amino acid phenylalanine,
well the UUC ; the ACU,
ACC, and ACG sequences the
amino acid ; and so on all
possible triplet and all other
acids.
