Chronic myelogenous leukemia (CML) is associated with the Philadelphia (Ph) chromosome. which results from a reciprocal translocation between chromosomes 9 and 22. This activates the abi oncogene by moving it from chromosome 9 and combining it with sequence located on chromosome 22. The new fusion gene. with chromosome 22 sequence at its 5’ end and chromosome 9-abl sequence at its 3’ end. gener...

abstract to identify the species, understanding the characteristics of the species, explore the possibility of speciation, mutations in the study population, and many other purposes. in this method for studying colchesin bath, karyotype use for immature worms. after reviewing the slide karyotype of polychaeta (nereis sp.) and observation and analysis of  50  plaque metaphase plate chromosome nu...

The abl oncogene is translocated from chromosome 9 to 22 in the creation of the Philadelphia (Ph1) chromosome. This article describes new translocation breakpoints identified in two patients with chronic myelogenous leukemia using Southern blotting and cloned human DNA probes from chromosome 9. The translocation breakpoints on chromosome 9 in both of these patients lie closer to the human cellu...

  Preparation of chromosome spreads and karyotype analysis in Blicca bjoerkna transcaucasica were carried out using 0.01% solution of colchicines and Phytohaemagglutinin (PHA) (20 µg g-1 body weight). The gill and kidney tissues were collected and let to stand in a hypotonic solution of 0.075 M KCl and then treated with a fixative (Carnoy's solution) in three steps. The chromosomes spreads were...
