Title: Control of Gene Expression
Description: The OHOLO Conferences have been convened annually from the Spring of 1956; the wide areas they have covered, from different and overlapping disciplines,

can be seen from the following list: 1956 Bacterial Genetics (not published); 1957 Tissue Cultures in Virological Research in Animals (not published); 1958 Inborn and Acquired Resistance to Infection in Animals (not published); 1959 Experimental Approach to Mental Diseases (not published); 1960 Cryptobiotic Stages in Biological Systems*; 1961 Virus-Cell Relationships**; 1962 Biological Synthesis and Function of Nucleic Acids**; 1963 Cellular Control Mechanism of Marcomoloecular Synthesis**; 1964 Molecular Aspects of Immunology**; 1965 Cell Surfaces**; 1966 Chemistry and Biology of Psychotropic Agents (not published); 1967 Structure and Mode of Action of Enzyme**; 1968 Growth and Differentiation of Cells "In Vitro"**; 1969 Behaviour of Animal Cells in Culture**; 1970 Microbial Toxins**; 1971 Interaction of Chemical Agents with Cholinergic Mechanisms**; 1972 Immunity in Viral and Rickettsial Diseases***.

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.
