Even though the nwnber of requests for reprints and the number of quotations in the Science Citation Index has indicated an ever-increasing interest in topics of organic polarography, I have often felt that the reason that some work is less known may well be because the papers were published in less accessible journals. Therefore, I was pleased when I was asked to prepare a selection of my papers on organic polarography for reprinting. This collection of papers may indicate some of the possibilities offered by polarography in the study of properties of organic compounds. The fact that the papers are published in one volume, not only makes the information more easily accessible for the reader, but also enables a direct comparison of related topics. The mode of selection is discussed in the Introduction. The papers reprinted in this volume are mostly based on work carried out in the J. Heyrovsky Institute of Polarography of the Czechoslovak Academy of Sciences in Prague, in cooperation with my co-workers. I would like to take this opportunity of thanking all of them for the pleasure I got from this cooperation on the solution of varying problems of organic electrochemistry .

The Cell Cycle: Gene-Enzyme Interactions focuses on the interaction of the genetic and enzymatic complements of a cell, as well as the control of genetic expression in bacterial cells. The selection first offers information on cell evolution and the thermodynamics and regulation of chromosome replication and cell division in Escherichia coli. Discussions focus on genome evolution, selection and thermodynamics, coordination between chromosome replication and cell division, and cellular response to nutritional alterations. The text then elaborates on temporal control of gene expression in bacteria, including rate of induced enzyme synthesis in synchronous populations; change in rate of induced enzyme synthesis and sequential gene replication; metabolic oscillations and the temporal control of enzyme synthesis; and DNA replication and the integration of cell growth and division. The publication examines synchrony and the formation and germination of bacterial spores and synthesis of macromolecules during the cell cycle in yeast. Topics include gene position and enzyme timing, synthesis of ribosomal and transfer RNA during the cell cycle, and analysis of synchrony during sporulation. The selection is highly recommended for readers wanting to study cell cycle.

Practical Polarography: An Introduction for Chemistry Students provides information pertinent to the fundamental aspects of practical polarography. This book presents the developments in polarography and provides descriptions and procedures that should be readily available for use with any available polarograph. Organized into eight chapters, this book begins with an overview of polarography that is widely employed in chemical analysis because the current-voltage curves show both the quantitative and qualitative composition of the solution. This text then explains the electrode in polarographic electrolysis, which consists either of a mercury pool at the bottom of the electrolytic cell that contains the solution under test, or of a special type of electrode of known potential. Other chapters consider the polarographic reduction of some metal ions and of some organic substances. The final chapter deals with the tables containing selected data of half-wave potentials measured against a saturated calomel electrode at 20-25°C. This book is a valuable resource for students, technicians, and chemists.
