Physico-chemical characteristics of human adenovirus type 6 DNA were studied. The sedimentation constant of adenovirus type 6 DNA was shown to be 32.7S. The intrinsic viscosity of DNA was on the average 93.8 dl/g. The average size of the molecular mass determined by the results of sedimentation and viscosimetry was 23.5 X 10(6) daltons which agreed favourably with the value calculated from the data of electron microscopic determination of the length of DNA molecule. The buoyant density of DNA in cesium chloride density gradient was 1.7126 g/cm3. The melting temperatures were 90.5 and 75 degrees C for 1 X SSC and 0.1 X SSC, respectively. Adenovirus type 6 DNA contained 52.6% GC pairs on the average.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D011232 Chemical Precipitation The formation of a solid in a solution as a result of a chemical reaction or the aggregation of soluble substances into complexes large enough to fall out of solution. Precipitation, Chemical
D002499 Centrifugation, Density Gradient Separation of particles according to density by employing a gradient of varying densities. At equilibrium each particle settles in the gradient at a point equal to its density.

D000260 Adenoviruses, Human Species of the genus MASTADENOVIRUS, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems. Serotypes (named with Arabic numbers) have been grouped into species designated Human adenovirus A-G. APC Viruses,APC Virus,Adenovirus, Human,Human Adenovirus,Human Adenoviruses
D014783 Viscosity The resistance that a gaseous or liquid system offers to flow when it is subjected to shear stress. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed) Viscosities
