<unk>  is the study of<unk>  at a<unk>  level. The field overlaps with other areas of<unk>  and chemistry, particularly genetics and biochemistry.<unk>  chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis and learning how these interactions are regulated.
Writing in Nature, William Astbury described<unk>  as:
"... not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical<unk>  for the corresponding<unk>  plan. It is concerned particularly with the forms of<unk> cal molecules and ..... is predominantly three-dimensional and structural - which does not mean, however, that it is merely a refinement of morphology - it must at the same time inquire into genesis and function."
