✦ Synopsis


New varieties of comma-free codes CFC of length 3 on the 4-letter alphabet are defined and analysed: self-complementary comma-free codes (CCFC), C 3 comma-free codes (C 3 CFC), C 3 self-complementary comma-free codes (C 3 CCFC), selfcomplementary maximal comma-free codes (CMCFC), C 3 maximal comma-free codes (C 3 MCFC) and C 3 self-complementary maximal comma-free codes (C 3 CMCFC). New properties with words of length 3, 4, 5 and 6 in comma-free codes are used for the determination of growth functions in the studied code varieties.

The hypothesis that the universal genetic code is adapted to double-strand coding is supported by its remarkable compatibility with the RNY comma-less hypothesis. Coding by a triplet code on a polynucleotide double-strand allows for enciphering of five additional messages with reference to a chosen
