    2 LEUKAEMIA CYTOGENETICS Fig. 1.—The myeloproliferative and lymphoproliferative disorders. mitoses there are three stages of interphase, a pre-DNA synthesis (G 1) phase, a DNA synthesis (S) phase, and a post-DNA synthesis (G 2) phase. During the S phase, the DNA and nuclear protein of the chromosomes are duplicated. During mitosis (Figs. 2 and 3), the chromosomes divide and usually each set forms a daughter nucleus; this process, called karyokinesis, is generally accompanied or followed by cytokinesis in which the cytoplasm divides, giving rise to two daughter cells. Mitosis is divided into several phases; during prophase, the chromosomes appear as separate identities, each consisting of two long threads (the chromatids) joined at a centromere. As
