Main description:

Chromosomes Today Volume 12 records the plenary proceedings of the 12th triennial International Chromosone Conference, presenting an overview of the current concerns in the developing studies of animal, plant and human cytogenetics. As well as giving an accurate historical record of the achievements in chromosome studies, this important series points the way forword, emphasizing the areas in which new developments will take place. Volume 12 explores the complete integration of molecular biology and cytogenetics, evaluating the concensus of the world's cytogeneticists concerning the nature and activities of the chromosome.It reinforces our view of the chromosome as the genetic organelle whose structure, behaviour and modification underlie our modern concept ofeukaryote genetics.
