The model which accounts more readily for the features of the highly rearranged chromosomes. Concept introduction: Chromosomal aberrations are changes in the normal structure of chromosome by addition, deletion, inversion and translocation. Chromosomal aberrations results in change in the gene order and inactivation of genes. If the genes involved in cell cycle are inactivated then cell cycle errors occurs which leads to cancer cells. There are two models regarding rearrangement of chromosomes which are studied that account for 2 to 3 % of all cancers which includes: Progressive Rearrangements Model (PRM) and Chromosome Catastrophe Model (CCM). Progressive Rearrangements model is where continuous chromosomal aberrations take place and several genes are rearranged. Chromosome Catastrophe Model is where the chromosome gets broken into several fragments and then stitched back together by Non Homologous End Joining (NHEJ).
