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
choose the correct option regarding rules

#Unit 8. Inheritance Biology

In a transduction experiment, phage P1 is grown on a bacterial host of genotype A+ B+ C+ and the resulting lysate is used to infect a recipient strain of genotype A– B– C–. The genes are in an order such that B is in the middle, and the distance between A and B is greater than the distance between B and C. Based on this information, which of the following least genotype?
