Detailed explanation-1: -The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).
Detailed explanation-2: -A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. DNA and RNA molecules are written in a language of four nucleotides; meanwhile, the language of proteins includes 20 amino acids.
Detailed explanation-3: -The body will need more tRNA types to code for all the codon sequences possible. Hence, the possible codon combination having four nucleotides is 256 and it would not work as amino-acid code.
Detailed explanation-4: -A codon is a DNA or RNA sequence of three nucleotides (a trinucleotide) that forms a unit of genomic information encoding a particular amino acid or signaling the termination of protein synthesis (stop signals).
Detailed explanation-5: -Four codons: Ala, Gly, Pro, Thr, Val. Five codons: none. Six codons: Arg, Leu, Ser.
