The Trypanosoma brucei nuclear genome contains about 100 minichromosomes of between 50 to 150 kilobases and about 20 chromosomes of 0.2 to 6 megabase pairs. Minichromosomes contain nontranscribed copies of variant surface glycoprotein (VSG) genes and are thought to expand the VSG gene pool. Varying VSG expression allows the parasite to avoid elimination by the host immune system. The mechanism of inheritance of T. brucei chromosomes was investigated by in situ hybridization in combination wit...Expand abstract
