Meiosis

This book details methods for preparing and examining meiotic tissues, cells, and chromosomes by electron microscopy, indirect immunofluorescence, fluorescent in situ hybridization, and live-cell imaging.

Each generation in a sexually reproducing organism such as a fly or a mouse passes through the bottleneck of meiosis, which is the specialized cell division that gives rise to haploid reproductive cells (sperm, eggs, spores, etc. ). The principal function of meiosis is to reduce the genome complement by half, which is accomplished through sequential execution of one round of DNA replication followed by two rounds of chromosome segregation. Within the extended prophase between DNA replication and the first meiotic division in most organisms, homologous maternal and paternal chromosomes pair with one another and undergo homologous recombination, which establishes physical connections that link the homologous chromosomes until the time they are separated at anaphase I. Recombination also serves to increase genetic diversity from one generation to the next by breaking up linkage groups. The unique chromosome dynamics of meiosis have fascinated scientists for well over a century, but in recent years there has been an explosion of new information about how meiotic chromosomes pair, recombine, and are segregated. Progress has been driven by advances in three main areas: (1) genetic identification of meiosis-defective mutants and cloning of the genes involved; (2) development of direct physical assays for DNA intermediates and products of recombination; and (3) increasingly sophisticated cy- logical methods that describe chromosome behaviors and the spatial and temporal patterns by which specific proteins associate with meiotic chromosomes.

Klappentext

The unique chromosome dynamics of meiosis have fascinated scientists for well over a century, but in recent years there has been a proliferation of new data concerning the pairing, recombination, and segregation of chromosomes. In Meiosis, expert researchers explore recent advances in three main areas: quantitative genetic methods for analysis of homologous recombination and chromosome pairing, development of direct physical assays for DNA intermediates and products of recombination, and cytological methods for characterizing chromosome behaviors and the patterns by which specific proteins associate with meiotic chromosomes. Meiosis: Volume 2, Cytological Methods, details methods for preparing and examining meiotic tissues, cells, and chromosomes by electron microscopy, indirect immunofluorescence, fluorescent in situ hybridization, and live-cell imaging. The methods in this volume are grouped for convenience by general types of organisms: fungi, plants and small animals (mostly invertebrates), and mammals. Composed in the highly successful Methods in Molecular Biology(tm) series format, each chapter contains a brief introduction, step-by-step methods, a list of necessary materials, and a Notes section which shares tips on troubleshooting and avoiding known pitfalls.

Comprehensive and cutting-edge, Meiosis: Volume 2, Cytological Methods is an essential guidebook, providing up-to-date and critical new protocols for the study of meiotic chromosome dynamics.
