Characterization of productive and sterile transcripts from the immunoglobulin heavy-chain locus: processing of micron and muS mRNA.

abstract：:Mutation in the REC2 gene of Ustilago maydis leads to defects in DNA repair, recombination, and meiosis. Analysis of the primary sequence of the Rec2 protein reveals a region with significant homology to bacterial RecA protein and to the yeast recombination proteins Dmc1, Rad51, and Rad57. This homologous region in th...
