Abstract:
Several decades of research have shown that macromolecular damage increases with age and that damage to protein, DNA, lipids, and other macromolecular components appears to be important factors in specific age-related diseases. The strongest evidence that macromolecular damage is a causative factor in aging comes from studies using manipulations that increase life span. However, it is currently unclear whether damage to macromolecules plays a role in the actual processes of aging. In other words, is macromolecular damage driven by aging or is it that damage to a key molecular component directly causes aging?

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
