dc.descriptionA hypothesis of the evolution of the genetic code is proposed, the leading mechanism of which is the nucleotide spontaneous damage leading to AT-enrichment of the genome. The hypothesis accounts for stability of the genetic code towards point mutations, the presence of code dialects, emergence of stop codons, emergence of the DNA double helix and the symmetry of the genetic code table. The assumption of the originally triplet structure of the genetic code has been substantiated. A hypothesis concerning the primary structure of the first gene and the first protein has been proposed.
