Explain the discovery, mechanism of action and function of AID
(activation-induced deaminase)?
SOMATIC HYPERMUTATION (Figures 7 and 8). Indeed, the discovery of AID provided the missing MSH2-deficient mice had previously been taken to indicate that somatic mutation is initiated by diversification at C:G pairs with MSH2-mediated recognition then triggering a subsequent stage of diversification at A:T pairs. Such a two-stage model was supportedations by the observation that CG-biased mutation was also a characteristic of somatic mutation in B-c nes9 and...

Response Questions Part A T。C. Use Only Information Below A. In addition to the dentist and patients A through G, why were 35 local HIV seropositive people included in this study? B. Of patients A through G, which ones had known risk factors for contracting HIV? What were some of the known risk factors at the time (realizing that this was the late 1980s when AIDS/HIV was first discovered)? How was it initially determined that patients E and F contracted...
