Gene conversion in Drosophila and the effects of the meiotic mutants mei-9 and mei-218.
Simple meiotic gene conversion tracts produced in wild-type females were compared with those from two meiotic mutants, mei-9 and mei-218. The positions and lengths of conversion tracts were determined by denaturing gradient gels and DNA sequencing. Conversion tracts in wild type averaged 885 base pairs in length, were continuous, and displayed no obvious hot spots of initiation. Some unusual co...
متن کاملHeteroduplex DNA in meiotic recombination in Drosophila mei-9 mutants.
Meiotic recombination gives rise to crossovers, which are required in most organisms for the faithful segregation of homologous chromosomes during meiotic cell division. Characterization of crossover-defective mutants has contributed much to our understanding of the molecular mechanism of crossover formation. We report here a molecular analysis of recombination in a Drosophila melanogaster cros...
متن کاملMandarin-English Information (MEI)
Mandarin-English Information (MEI) is one of the four projects selected for the Johns Hopkins University Summer Workshop 2000. We plan to develop technologies for using written queries to search spoken documents (cross-media) between English and Mandarin Chinese (cross-language). Our research focus is on the integration of speech recognition and machine translation technologies in the context o...
