The three nitrogen bases of the genetic code are never arranged in an overlapping or overlapping manner. (If the genetic code overlaps, four amino acids will be specified by 6 nitrogen bases and seven by 9 nitrogen bases. On the other hand, if the genetic code is not overlapped, two amino acids will be specified by 6 nitrogen bases and three amino acids will be specified by 9 nitrogen bases). In 1965, scientist Hargobind Khorana proved that the nitrogen bases of the genetic code are non-overlapping. For example- CGUCGCCGA.
