DNA is undoubtedly an exceptionally important biological macromolecule; it is the medium encoding the information that directly or indirectly determines the structural and functional properties of all living organisms. Small structural differences in DNA induced, for example, by particle bombardment or electromagnetic radiation, often have far-reaching consequences and may lead to deleterious s...

A detailed understanding of the function of a biological macromolecule requires knowledge of its three-dimensional structure. Most atomic-resolution structures of biological macromolecules have been solved either by x-ray diffraction in single crystals or by nuclear magnetic resonance (NMR) in solution. This review surveys the method of NMR structure determination. First a brief introduction to...

The purpose of the flocculation operation is not only to remove substance causing turbidity, but also give particles with ability be trapped in subsequent operations. This paper discusses process generating floc, sedimentation characteristics, separation effect and so on, when macromolecule heavy metal flocculant CSAX used water treatment, especially for ions turbidity coexisting system. resear...

Molecular biology investigates the structure and function of biochemical systems starting from their basic building blocks: macromolecules. A macromolecule is a large, complex molecule (a protein or a nucleic acid) that usually has inner mutable state and external activity. Informal explanations of biochemical events trace individual macromolecules through their state changes and their interact...
