Molecular Regulation of Nuclear Events in Mitosis and Meiosis presents papers from researchers in various fields engaged in the scientific study of molecular mechanisms involved in the control of nuclear events in meiotic and mitotic cell activity. Various articles in the book discuss a wide range of topics such as the development of cytoplasmic activities that control chromosome cycles during maturation of amphibian oocytes; dynamics of the nuclear lamina during mitosis and meiosis; role of protein phosphorylation in xenopus oocyte meiotic maturation; and cell cycle studies of histone modifications. Molecular and cell biologists, oncologists, and biochemists will find the book invaluable.
