Translocation is a type of structural aberration of the chromosome where a segment of chromosome gets translocated to another chromosome. Ring chromosomes usually result from two terminal breaks in both chromosome arms, followed by fusion of the broken ends, or from the union of one broken chromosome end with the opposite telomere region, leading to the loss of genetic material [].Alternatively, they can be formed by fusion of subtelomeric sequences or telomere-telomere fusion with no deletion, resulting in complete … In another study, a woman with isolated thrombocytosis diagno-ses with follicular lymphoma was reported as JAK2 V617F mutation negative and Philadelphia chromosome positive [5].

DNA is the stuff our genes are made of… The organization of total sum of genetic information (or genome) of an organism is in the form of double- stranded DNA, except that viruses may have single- stranded DNA, single-stranded RNA or double- stranded RNA genomes. In many viruses and prokaryotes, the genome is a single linear or circular molecule. In eukaryotes, the nuclear genome consists of linear chromosomes (usually as a diploid set) and the mitochondrial and chloroplast (in plants) genomes are small circular DNA molecules. In 1952, Watson and Crick proposed that DNA is a double helix which is known to have alternative forms. Termed the Philadelphia (Ph) chromosome, it is a shortened chromosome 22 resulting from a reciprocal translocation, t(9;22)(q34;q11), between the long arms of chromosomes 9 and 22.
