Abstract:
In a previous paper, the authors defined a numerical characterization of
DNA primary sequences. A DNA primary sequence was reduced to a
few of binary sequences, based on the classifications of the four nucleic
acid bases. The reduced sequences are called the characteristic
sequences. For each characteristic sequence, we associated two 2x2
matrices, the elements of which are given by the frequency of
occurrence of all (0,1) triplets in the characteristic sequence. In this
paper, we use eigenvalues of the new matrices to characterize the
biological functions of purine-pyrimidine, amino-keto groups and
weak-strong H-bonds, respectively.
