Why would concluding that there is a lack of pairing of the bases contradict wilkins' and franklin's data

The photo called photo 51 A was produced by the Rosalind Franklin who was working on the structure of DNA.

She produced the picture of DNA with the help of the X-ray diffraction technique and found that DNA structure is helical in appearance.

The photo was later used by the Watson and Crick who gave the structure of the DNA using the photo as reference. They showed the chemical bonds formed between the two strands of DNA.

They used the Chargaff rule of complementary base pairing that A will bind T and G will bind C which if not followed or lacks will produce an alignment which will not allow the formation of a helical structure. The lack of base pairing will allow the formation of just single-stranded structure and not double-helical structure.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
