Histograms showing the distributions of the frequency of alanine, serine and leucine in the alanine frequency cluster from the BLOCKS database and from the random protein sequences. a. Frequency of alanine, correlation coefficient between two frequency vectors is 0.986. b. Frequency of serine, correlation coefficient between two frequency vectors is 0.984. c. Frequency of leucine, correlation coefficient between two frequency vectors is 0.998.
