The function of DNA is to specify protein sequences. The four-base "alphabet" used in nucleic acids is translated to the 20 base alphabet of proteins (plus a stop signal) via the genetic code. The code is neither overlapping nor punctuated, but has mRNA sequences read in successive triplet codons un
A model for topological coding of proteins is proposed. The model is based on the capacity of hydrogen bonds (property of connectivity) to "x conformations of protein molecules. The protein chain is modeled by an n-arc graph with the following elements: vertices ( -carbon atoms), structural edges (p
The main theories which have been suggested to explain the origin of genetic code organization are discussed. The coevolution theory, which considers the genetic code as a map of the biosynthetic relationships between amino acids, seems to be based on a mechanism that links it closely to certain sta
