This revised edition provides a survey of current biochemistry and molecular biology in the form of a dictionary. It contains short but informative entries arranged under more than 17,000 headwords. It is intended as a handy reference of first resource for those seeking information outside their immediate knowledge area or for those who need to refresh their memory of fundamental knowledge. This revised edition has been fully up-dated in order to include the new information that has been discovered since the original edition was published in 1997.

The unique feature of this book's first edition was the presentation of a unified approach to the molecular biology of prokaryotes and eukaryotes. The success of this approach, and its continuation, is the result of a long string of discoveries showing similarities in solutions to biological problems that often extend across many or even all species. A six-part organization covers genes, proteins, gene expression, DNA, the nucleus, and cells. For individuals in the science community interested in genetics.
