61Mechanical properties of DNA — The mechanical properties of DNA, which are directly related to its structure, are a significant problem for cells. Every process which binds or reads DNA is able to use or modify the mechanical properties of DNA for purposes of recognition,… …
62Nucleic acid double helix — Double helix redirects here. For other uses, see Double helix (disambiguation). Two complementary regions of nucleic acid molecules will bind and form a double helical structure held together by base pairs. In molecular biology, the term double… …
63Chemistry — For other uses, see Chemistry (disambiguation). Chemistry is the science of atomic matter (that made of chemical elements), its properties, structure, comp …
64DNA condensation — refers to the process of compacting DNA molecules in vitro or in vivo.[1] Mechanistic details of DNA packing are essential for its functioning in the process of gene regulation in living systems. Condensed DNA often has surprising properties,… …

66ECHIDNA - High Resolution Powder Diffractometer — ECHIDNA is the name of the new neutron High Resolution Powder Diffractometer at Australia s new research reactor OPAL, ANSTO. The instrument serves to determine the crystalline structures of materials using neutron radiation analogical to X ray… …
67economic systems — Introduction the way in which humankind has arranged for its material provisioning. One would think that there would be a great variety of such systems, corresponding to the many cultural arrangements that have characterized human society.… …
68Triton (moon) — Triton Voyager 2 photomosaic of Triton s sub Neptunian hemisphere. The bright, slightly pinkish, south polar cap at bottom is composed of nitrogen and methane ice and is streaked by dust deposits left by nitrogen gas geysers. The mostly darker… …
69Event symmetry — The term Event symmetry describes invariance principles that have been used in some discrete approaches to quantum gravity where the diffeomorphism invariance of general relativity can be extended to a covariance under any permutation of… …
70Catastrophe theory — This article refers to the study of dynamical systems. For other meanings, see catastrophe. In mathematics, catastrophe theory is a branch of bifurcation theory in the study of dynamical systems; it is also a particular special case of more… …
