The relationships are differentiated in the structure of the genetic code, in the function of the genetic code as well as between the structure and the function of the genetic code. A table is included which represents the genetic code discovered due to the research carried out by Gamow, Nirenberg, Khorana, Crick, Marshal, Schoeck, Thomas, Icheas, Ratner, etc. In contrast with the presentation, in various papers of molecular biology, of the table with the genetic code, the author also pointed out the following: 123 the delimitation of S families as well as of the K classes of codons according to the fundamental structure of the genetic code; the delimitation of F families of codons according to the fundamental function of the genetic code: the counting of codons according to S families as well as to F families.
