#Unit 3. Fundamental Processes

There were four rules of parity given by Erwin Chargaff 

1) Base A in one strand of the duplex is matched by (T) in the other strand, and base G in one strand of the duplex is matched by a complementary base (C) in the other strand

2) equal amounts of A and T, and equal amounts of C and G, in each single strand of the duplex. 

3) Purines in non-template strand applies more closely to Exons

4) GC content tends to be greater in exons than in introns
