TL;DR: The previously discovered linear relation between the base composition of DNA, expressed in percentage of guanine plus cytosine bases, and the denaturation temperature, T m, has been further investigated and it appears that the measurement of the T m is a satisfactory means of determining base composition in DNA.

TL;DR: An extension of the spectral range of measurement toward optically active absorption bands in the far ultraviolet is expected to yield new information about the rotatory power of the peptide bond and thus enhance the interaction of theory and observation that has already proved fruitful.
Abstract: Publisher Summary This chapter focuses on the capacity of the optical rotatory methods to discern mixtures of this conformation with disordered regions. It discusses the manner in which theoretical considerations have provided the forms into which rotatory data are currently cast, the calibration of their constants by studies of synthetic polypeptides in known conformation, and then, the application of these equations and scales in the structural interpretation of the rotatory dispersion of proteins. This pattern of analysis undergoes refinement and revision as these methods are applied to new species of polypeptide and protein in concert with other means of conformational assignment. An extension of the spectral range of measurement toward optically active absorption bands in the far ultraviolet is expected to yield new information about the rotatory power of the peptide bond and thus enhance the interaction of theory and observation that has already proved fruitful.

TL;DR: A high degree of homology was found between pairs of T-even phage DNA and between the DNA from T3 and T7, and no indication of homologous links were found between DNA fromT-even and T-odd phages, nor between these and Escherichia coli DNA.

Journal ArticleDOI
TL;DR: It is shown in this paper that rotor speed does not influence the sedimentation of samples up to molecular weight 16·106 until a critical high velocity is reached, which is the limit of the speed dependence in sedimentation.

Journal ArticleDOI
TL;DR: The effect of temperature of ultraviolet radiation on the cross-linking of desoxyribonucleic acid (DNA) in Salmonella typhimurium was measured at two different ionic strengths to show the biological and physical heterogeneity of denatured ultraviolet- irradiated DNA.
