Bases of Active vs Inactive DNA Fig from Naveh-Many and Cedar

Bases of Active vs Inactive DNA Fig What is the general rule about gene activity and methylation? from Naveh-Many and Cedar

Bases of Active vs Inactive DNA Fig What is the general rule about gene activity and methylation? active genes are hypomethylated inactive genes are hypermethylated from Naveh-Many and Cedar

Fig active genes are hypomethylated inactive genes are hypermethylated Cause vs Correlation from Naveh-Many and Cedar
