Biochemistry, DNA Repair

DNA is the most important molecular aspect of our bodies. It constitutes the expression and action of so many different processes within our cells and makes each person function in the way a human should. Every day, the strands of DNA that make up the various cells and components in our body experience billions of different types of damage and lesions in their makeup. Some of this damage is a result of the regular metabolic processes inside individual cells to produce energy and synthesize more material.

Another portion of the damage comes from a wide array of environmental and external factors. Nonetheless, the damage that DNA receives daily requires correction for cells to continue functioning and working for our benefit. Without continuous active repair, the integrity of our genome would become compromised. DNA repair involves many different types of actions that a cell can take to make these fixes occur and displays specificity for certain types of damage and strain.
