Human rotaviruses containing rearranged genomes were found to package up to 1,800 additional base pairs in virus particles. The viruses compared were indistinguishable in respect of their particle diameters and their apparent S values. Particles containing rearranged genomes were found to be of a higher density than rotavirus particles containing a standard genome as determined by equilibrium density ultracentrifugation. The increase in density was directly proportional to the number of additionally packaged base pairs.

UI MeSH Term Description Entries
D009024 Morphogenesis The development of anatomical structures to create the form of a single- or multi-cell organism. Morphogenesis provides form changes of a part, parts, or the whole organism.
D009154 Mutation Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations. Mutations
D002500 Centrifugation, Isopycnic A technique used to separate particles according to their densities in a continuous density gradient. The sample is usually mixed with a solution of known gradient materials and subjected to centrifugation. Each particle sediments to the position at which the gradient density is equal to its own. The range of the density gradient is usually greater than that of the sample particles. It is used in purifying biological materials such as proteins, nucleic acids, organelles, and cell types. Isopycnic Centrifugation
