Question 9-6
How can only four nucleotide bases code for the
vast number of proteins in living organisms?
1. The four bases are translated differently in
different organisms.
2. There are billions of possible combinations
of sequences of the four nucleotides.
3. All organisms have the same proteins.
4. Mutations make the meaning of the
nucleotides different from their normal
meaning.
