Early geneticists wondered how only four nucleotides can specify the sequence of 20 amino acids in proteins. They hypothesized t

hat there must be a code that linked the nucleotide sequence in a gene to the amino acid sequence in a protein. Each nucleotide code is called a codon. Today we know that there is a genetic code in which __________nucleotide(s) code(s) for each amino acid.

Explanation:

3 is the answer. 43 or 64 is the number of possible 3-letter codes that can be formed.

more than one codon can codes for the same amino acid
