Paramecium Genetics and Epigenetics

Langue : Anglais

Couverture de l’ouvrage Paramecium

The techniques used to decipher the genetic makeup of species as well as epigenetic mechanisms are essential for explaining life forms and studying their DNA. As a eukaryotic model, Paramecium is well suited for genetic analysis. Taking a rather unconventional view of genetics, Paramecium: Genetics and Epigenetics explores how to use this protozoan as a basis for studying complex cells.

The book discusses various aspects of Paramecium, including the cortex, the cytoplasm, nuclei, asexual fission, conjugation, autogamy,macronuclear regeneration, cytogamy, life cycle phases, and behavior. It examines the assorted mating types of the genus and how these mating types are determined. It also elucidates some techniques that identify genetically defined genes with the DNA from a library that comprises those genes and details the genetic, epigenetic, chemical, and molecular facets of several different traits. In addition, the authors chronicle the history and reemergence of investigating RNA and DNA in Paramecium.

With many powerful tools now available, Paramecium research is entering a new frontier in molecular biology. A full account of Paramecium genetics, this book presents a wealth of time-consuming observations and remarkable phenomena that will lead to a better understanding of complex cells.

Geoffrey Beale, John R. Preer Jr.,
In this definitive reference, the author lends 50 years of experience in the subject to Paramecium Genetics. Paramecia were among the first organisms used to clarify genetic mechanisms, and though they have been overtaken by other organisms in genetics research, it is still of historical interest to geneticists. The text is written in an accessible, informal style and incorporates historical aspects. It covers features of the organism itself, general morphology and reproduction, mating types, methods of genetic analysis, endosymbionts and mitochondria, immobilization antigens, micro-and macronuclei, ribosomal DNA, telomeres, behavioral mutants and epigenetic phenomena.
