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...
