Abstract excerpt
The CpG dinucleotide is present at approximately 20% of its expected frequency in vertebrate genomes, a deficiency thought due to a high mutation rate from the methylated form of CpG to TpG and CpA. We examine the hypothesis that the 20% frequency represents an equilibrium between rate of creation of new CpGs and accelerated rate of CpG loss from methylation. Using this model, we calculate the expected reduction...
