All recombination models postulate one or more recombination intermediates that are joint molecules containing two homologous parental molecules. A spike of branched DNA molecules not seen in DNA from mitotic cells was found in the two-dimensional gel analysis of meiotic DNA from S. cerevisiae. The mass of molecules in the spike, the timing of its(More)
The granular structure of soils, sands and other geomaterials make them amongst the most difficult engineering materials to model. Most engineering theories are based upon the results of laboratory experiments and pay little or no attention to the unique micromechanics of such materials. Recent advances in our understanding of the micro-and meso – physics(More)
