[i] (Top) The number of total ApT (with or without modification) and 6mApT sites in DNA molecules fully mapped to the MAC. Both W and C are counted. Percentage of DNA methylation is also calculated [6mApT/(total ApT)]. (Bottom) The number of full-6mApT and hemi-6mApT duplexes. Note that each full-6mApT duplex contains two 6mA sites, whereas each hemi-6mApT duplex only contains one site. Percentages of full-6mApT and hemi-6mApT duplexes are also calculated.
