The organisation and behaviour of chromosomes is central to genetics and the equal segregation of genes and chromosomes into daughter cells at cell division is vital. This text aims to provide a clear and straightforward explanation of these complex processes.Following a brief historical introduction, the text covers the topics of cell cycle dynamics and ChromosomesChromosomes.572.8/7Sumner A.
