Why is variability required in both BCRs/antibodies and TCRs>?
Variability is required in both T cell receptor and B cell receptor in human body
The portal for the antigen produced by specific microgansm to attach is different
Only if variability is present between these receptors then only wide variety of antigen and the microorganism can be destroyed by the body
Many somatic changes in DNA and germline DNA made it possible for both these to have variability and destroy many antigens comming into body and protect it .
