Parity rules by Erwin Chargaff

Rule of complementarity (First parity rule)

Rule of Equal amount applies more closely to introns than to exons (Second parity rule)

Cluster rule – Purines in nontemplate strand applies more closely to Exons (Third parity rule)

GC Rule- GC content tends to be greater in exons than in introns (Fourth parity rule
