The participants who attend these Conference are drawn from different scientific institutions in Israel and from many foreign countries ; they are engaged in fields of study which represent widely divergent approached to biology. Thus a distinguishing feature of the OHOLO meetings has been their multi-disciplinary nature. these small international conferences are also characterized by their relaxed atmosphere, with ample time for informal as well as formal discussions. The present volume contains almost all the papers presented at the eighteenth OHOLO Biological Conference, devoted to Strategies for the Control of Gene Expression, held at Zichron-Yaakov, Israel, on March 27-30, 1973. In order to obtain an overview of the broad spectrum of knowledge in the field, and to summarize a considerable number of closely related topics, noted investigators were invited to discuss and analyze together the goals already achieved and to speculate on future trends in the study of gene expression.

More than 200 participants (including some twenty from overseas) took part in this meeting, and the twenty-four papers presented summarize much data gathered in extensive studies.
