Riassunto

In the past few years, the body of experimental work on the structure, function and assembly processes of mitochondria has expanded rapidly. No one person can believe himself or herself completely in control of the burgeoning literature without possessing serious omissions or blind spots. In the present monograph I have attempted a critical evaluation of the literature. I believe that the common thread of single authorship outweighs the shortcomings of one person presenting many disparate viewpo,ints. It is my hope that the end product represents a comprehensive and coordinated review of the subject matter to the present date. Although the bulk of this monograph was completed by October 1974, I have made some attempts to update several of the sections at later times. Albany, N. Y. , November 1975 H. TEDESCHI Contents A.
