WebThese are comprised of 20 unique amino acids, and each is coded for by a stretch of DNA known as a codon. Codons are always 3 base-pairs (nucleotides) in length. DNA is made of 4 unique nucleotides; ( A )denine, ( G )uanine, ( C )ytosine and ( T )hymine. This means that there are 64 unique codons that can be made with these 4 bases (4*4*4). WebMethionine and tryptophan are the only two amino acids that are coded for by just a single codon (AUG and UGG, respectively). The other 18 amino …

WebJul 9, 2024 · Explanation: A codon codes for each specific amino acids, and is made up of a triplet of nucleotides, i.e. three nucleotides. Therefore, we can say that three nucleotides will code for one amino acid. Therefore for 900 nucleotides, we would make: 900nucleotides 3nucleotides/amino acid = 300 amino acids Answer link WebApr 9, 2024 · That there is only one genetic code is powerful evidence that all of life on Earth shares a common origin, especially considering that there are about 10 84 possible combinations of 20 amino acids and 64 triplet codons.
