GENETIC HETEROZYGOSITY IN UNREPLICATED BACTERIOPHAGE h RECOMBINANTS
Bacteriophage crosses using density-labeled parents have been carried out under conditions restricting DNA synthesis. The parental material and genetic contributions to progeny manifesting recombination within a genetic interval sufficiently short to exhibit high negative interference have been examined. The unreplicated products of recombination isolated as phage particles appear to contain lo...
متن کاملThe distribution of crossovers along unreplicated lambda bacteriophage chromosomes.
The distribution of crossovers along unreplicated chromosomes of bacteriophage lambda has been examined by determining the density distributions and genotypes of particles in the progenies of crosses of density-labeled by ordinary parents in the presence of genetic blocks to replication. The Red and Rec systems combined produce crossovers primarily near the ends (especially the right end) of th...
متن کاملHeterozygosity and Genetic Distance
In the mid-1960s protein electrophoresis revolutionized the study of population genetics and evolution. This technique revealed an extensive amount of genetic polymorphism existing in natural populations and, at the same time, provided a powerful tool to examine the evolutionary relationships of closely related species.1’2 In 1972 I developed a statistical method by which one can measure the ge...

متن کاملHeat Induced Capsid Disassembly and DNA Release of Bacteriophage λ
Successive structural changes of bacteriophage λ upon heating were characterized with quantitative experimental methods. In the commonly used Tris-Mg buffer, differential scanning calorimetry measurements first established that the protein capsid of λ phage melts at 87 °C and its genomic DNA melts at 91 °C. Interestingly, prior to the capsid melting, λDNA was found to escape out of the capsid a...
