Detailed explanation-1: -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-2: -The mRNA bases are grouped into sets of three, called codons. Each codon has a complementary set of bases, called an anticodon. Anticodons are a part of transfer RNA (tRNA) molecules.
Detailed explanation-3: -There are 3 STOP codons in the genetic code-UAG, UAA, and UGA. These codons signal the end of the polypeptide chain during translation. These codons are also known as nonsense codons or termination codons as they do not code for an amino acid.
Detailed explanation-4: -Each codon corresponds to a single amino acid (or stop signal), and the full set of codons is called the genetic code. The genetic code includes 64 possible permutations, or combinations, of three-letter nucleotide sequences that can be made from the four nucleotides.
Detailed explanation-5: -However, a triplet code produces 64 (43 = 64) possible combinations, or codons.
