Recombination and mutagenesis of DNA ,,M and .R. A polypeptide which governs the specificity of the system is determined by .S. The gene product of .M is the modification enzyme which also interacts with the product of the .R gene, the restriction endonuclease, in the cleavage process. In the above examples the phage grown on strain K wo

Expression of cloned genes in animal cells,growth in HAT medium. The observation that carrier DNA greatly enhanced the transformation frequency led to successful attempts to transfer single copy eukaryotic genes using total genomic DNA . Wigler and colleagues then demonstrated that unlinked, non-selectable genes could be cotransformed whe

A point to emphasize, however, is that this fall of blood pressure, which can be quite prolonged, must be due mainly to vasodilation in the splanchnic bed, because this, more than any other, is the

Responses of Whole Plants to Air Pollutantsype” pollution). Photochemical smog is produced in the atmosphere by complex photochemical reactions involving nitrogen oxides and hydrocarbons from sources such as auto exhaust gases and electric power plants. A similarly serious air pollution problem has now emerged in large urban cities in develo

Reintgesse controversies are best resolved when the bilateral relations between the states concerned are otherwise good, when it is in their mutual interest to reach agreement, or when the asymmetry between the states involved is clearly defined and the more powerful state decides to end the dispute.
