corrects damage to the DNA molecules that encode its genome. In human cells, both normal metabolic activities and environmental factors such as radiation can cause DNA free system error repair software damage, resulting in as many as 1 million individual molecular lesions per error prone repair system cell per day.[1] Many of these lesions cause structural damage to the DNA molecule and can alter or eliminate error free dna repair the cell's ability to transcribe the gene that the affected DNA encodes. Other lesions induce potentially harmful mutations in the cell's genome, which affect the survival of its daughter cells after how to fix system error it undergoes mitosis. As a consequence, the DNA repair process is constantly active as it responds to damage in the DNA structure. When normal repair processes fail, and when cellular apoptosis does not occur, irreparable DNA damage may occur, including double-strand breaks and DNA crosslinkages (interstrand crosslinks or ICLs).[2][3] This can eventually lead to malignant tumors, or cancer as per the two hit

hypothesis. The rate of DNA repair is dependent on many factors, including the cell type, the age of the cell, and the extracellular environment. A cell that has accumulated a large amount of DNA damage, or one that no longer effectively repairs damage incurred to its DNA, can enter one of three possible states: an irreversible state of dormancy, known as senescence cell suicide, also known as apoptosis or programmed cell death unregulated cell division, which can lead to the formation of a tumor that is cancerous The DNA repair ability of a cell is vital to the integrity of its genome and thus to the normal functionality of that organism. Many genes that were initially shown to influence life span have turned out to be involved in DNA damage repair and protection.[4] Play media Paul Modrich The 2015 Nobel Prize in Chemistry was awarded to Tomas Lindahl, Paul Modrich, and Aziz Sancar for their work on the molecular mechanisms of DNA repair processes.[5][6] It's two types:- 1 nucleotide excision repair, 2 base excision repair Contents 1 DNA damage 1.1 Sources of damage 1.2 Types of damage

Recent data indicate that the fidelity of DNA double-strand break repair may be particularly relevant to the aging process. In general, double-strand breaks can be repaired by two distinct pathways: homologous recombination and non-homologous end joining. End joining is typically more error-prone and therefore mutagenic. This is particularly true of ìbackupî end-joining pathways that operate independently of the ligase IV and Ku proteins, have slower repair kinetics, and often involve substantial loss of genetic information. In spite of their potential importance in aging, these alternative end joining pathways are often masked by other repair mechanisms and therefore remain largely uncharacterized. To investigate the molecular mechanisms of alternative end joining, we have developed transgenic systems in Drosophila melanogaster that enable us to create double-strand breaks at specific genomi
