The focus of this book is on centrioles — small organelles adjacent to the nucleus in all human and animal (eucaryotic) cells. It provides the findings and critical analyses of over 750 articles written in this century.In addition to centrioles, the topics include: centrosomes, chromosomes, microtubules and kinetochores, cell division and duplication, and tumor development. The book also includes discussions on centriole dynamics and electromagnetics effects. It concludes with a chapter on centriole errors — particularly cells with supernumerary centrioles.The book is intended for students, scholars, and researchers studying and working in the field of nuclear mechanics. In addition to the book content, it provides a guide for literature investigation.
