Temporal changes in phosphoglycerate kinase coding sequences: a quantitative measure.
The ratio of the average of the square of the number of the nucleotides to that of the random sequence of the same strand bias is proposed as a quantitative measure of evolution in some coding DNA sequences. Applying this measure to the phosphoglycerate kinase gene we observe a monotonic rise of the ratio with evolution. We present an interpretation of this data on some bacteria.
