Extraordinary new functions for the nucleolus have begun to appear, giving the field a new vitality. This book examines these recent discoveries. It emphasizes nucleolar proteins while also including the crucial importance of nucleic acids.

Within the past two decades, extraordinary new functions for the nucleolus have begun to appear, giving the field a new vitality and generating renewed excitement and interest. These new discoveries include both newly-discovered functions and aspects of its conventional role. The Nucleolus is divided into three parts: nucleolar structure and organization, the role of the nucleolus in ribosome biogenesis, and novel functions of the nucleolus.

Covers recent discoveries on novel functions of the nucleolus. Emphasizes nucleolar proteins while also including the crucial importance of nucleic acids. Includes chapters on nucleolar ultrastructure, the locations and dynamics of nucleolar components, and on regulatory systems. Includes supplementary material: sn.pub/extras
