sequence, and so co-polymers were made in which the proportions of the two nucleotides were varied and the percentages of the amino acids incorporated determined. These were then compared with the statistical composition of the RNAs. A breakthrough came when Nirenberg and Phil Leder developed the fi lter-binding assay that enabled assignments to be made to a single triplet. And so it was that C...

large tracts of this are nature reserves, the study found that habitats with the highest diversity and abundance of these species were largely outside the protected forest areas. “Drawing on historical records and comparisons with other West Indian islands, this study found most of St Lucia’s native forest species have declined significantly in population size with some at critically low levels...
متن کاملDr TIM: Ray-tracer TIM, with additional specialist scientific capabilities
We describe several extensions to TIM, a raytracing program for ray-optics research. These include relativistic raytracing; simulation of the external appearance of Eaton lenses, Luneburg lenses and generalised focusing gradient-index lens (GGRIN) lenses, which are types of perfect imaging devices; raytracing through interfaces between spaces with different optical metrics; and refraction with ...
متن کاملNucleic Acids of Chloroplasts and Mitochondria in Swiss Chard
Nucleic acids in young leaves of Swiss chard have been studied by light and electron microscope techniques. Leaf DNA has also been characterized by density gradient centrifugation and shown to contain a minor band of higher guanine plus cytosine (GC) content, presumably attributable to chloroplasts. The chloroplasts were faintly stained by the Feulgen reaction; radioautography demonstrated the ...
