Description

Reproduction: Molecular, Subcellular, and Cellular is a collection of papers presented at the Twenty-Fourth Symposium of The Society for Developmental Biology, held at Carleton, Minnesota in June 1965. The papers in the compendium focus on the clarification and definition of specific aspects of reproduction at different levels of biological organization. Topics discussed include the transcription and translation of genes; interactions between plant viruses and host cells; chromosome reproduction in mitosis and meiosis; cell and tissue interactions in the reproduction of cell type; and aging as a consequence of growth cessation. Biologists, microbiologists, and cytologists will find the book insightful.
