Meiotic Chromosomes and Meiotic Mechanisms bonus for geneticists, who have yeast as a very handy model, and a curse for evolutionists, who look for a primitive and perhaps simple kind of meiosis. In fact, few eukaryotes can be pointed out as absolute asexual, that is lacking sex reproduction and the vestiges of sexual ancestors. Perhaps Sou

The Nuclear Envelope at the Attachment Sites of Mammalian Meiotic Telomerest aspects of this process. For example, an essential step during meiotic prophase is the synapsis of homologous chromosomes. In order to find each other, homologous chromosomes, which initially occupy different nuclear territories, have to move. However, the mechanisms governing long distance chromo

Interphase Cytogenetics in Understanding Chromosome and Telomere Dynamics During Prophase I: Implica whole chromosomes and subregions in nuclei, which usually lack chromosome-specific landmarks accessible to conventional staining methods. The possibility to simultaneously label several targets in interphase nuclei has led to widespread use of this technique in diagnostic settings and investigation

Chromosomal Translocations in Leukaemia: Emerging Networksnetic analysis. Almost 40 years ago it was noted that a peculiar small chromosome was a constant feature of chronic myeloid leukaemia (CML) (Nowell and Hungerford, 1960). This so-called Philadelphia chromosome was initially thought to be a partially deleted G-group chromosome. However, it became app

Genes and Sex Determination in Medakawhy such a simple and highly conserved biological phenomenon as the existence of males and females should be controlled by so different mechanisms like the ratio of X chromosomes to autosomes for instance in the fruit fly . and the worm . or the presence of a Y chromosome in male mammals.
