Abstract excerpt
Somatic mutation in immunoglobulin genes is localized to a 2-kilobase region of DNA surrounding and including rearranged variable (V), diversity, and joining (J) gene segments encoding heavy and light chains. To examine the structural basis for targeted mutation, we developed an assay to score mutation on plasmid substrates by using a reporter gene: a bacterial gene encoding an amber-suppressor tRNA molecule was...
