Chromosome techniques

Chromosome Theory and Practice, Third Edition focuses on chromosome research.The book first discusses pre-treatment and hypotonic treatment. Pre-treatment for clearing the cytoplasm and softening the tissues; separation of chromosomes and clarification of constrictions; and hypotonic treatment for chromosome spread are described. The text also explains fixation and processing, including fixing of fluids and mixtures and air-drying techniques for chromosome study.The selection also discusses methods for special materials. Study of division in embryosac mother cells; study of chromosomes from thallophytes; salivary gland, lamp brush, and pachytene chromosomes; spiral structure; and secondary constriction are explained. The text also discusses microscopy, including ordinary light microscopy, high resolution autoradiography, and light microscope autoradiography.The book discusses study of plant chromosomes from tissue culture; chromosome analysis following short- and long-term cultures in animals, including man; and chromosome analysis from malignant tissues. The text takes a look at the banding patterns of chromosomes, including banding pattern techniques, C-banding, and representative schedules for comparative study of different banding patterns. The book further describes somatic cell fusion and the chemical nature of chromosomes, proteins, and enzymes.The text is a vital source of information for readers wanting to conduct research on chromosomes.
