Safeguarding Genome Integrity Through Extraordinary DNA Repair(Name)(Course Number)(Instructor`s Name)(Date)Safeguarding Genome Integrity Through Extraordinary DNA RepairSummaryThe Lawrence Berkeley National Laboratory scientists, Gary Karpen, Irene Chiolo and their colleagues, from the U.S. Department of Energy have been studying the DNA of the fruit fly Drosophila melanogaster. They have discovered a process repairing broken double-strands with the use of heterochromatin, a chromatin mostly known to contain “junk” DNA. They have discovered that heterochromatin is not junk at all. It plays an important role where it maintains the integrity of the chromosomes during cell division. The chromosomes` integrity during this process is important because it is necessary for the normal function of the cells. Aberrations in the chromosomes (e.g. onset of cancer cell formation) generate severe consequences for the stability of the genes. Two methods for the repair were noted. One...
