We have 4 nucleotides A, T, G and C. So total number of combination for codons will be 4*4*4=64. Total there will be 64 codons for producing 20 amino acids, which are generally found in nature. So the 400 amino acids will also be formed from these set of 64 codons.Click to see full answer. Also to know is, how many codons are needed for each amino acids?Answer and Explanation: Three codons are needed to specify three amino acids. how many bases are needed to make 3 amino acids? Explanation: Each amino acid is coded by 3 bases, and so three amino acids would need: 3⋅3=9 bases. In respect to this, how many bases are needed for 4 amino acids? Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids. Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.Which amino acid has 4 codons?For example, six codons specify leucine, serine, and arginine, and four codons specify glycine, valine, proline, threonine, and alanine. Eight amino acids have two codons, whereas there is one codon each for methionine and tryptophan.
