Agentes que lesionan al AND: errores de replicación, luz ultravioleta (rayos UV) y radiación electromagnética de alta energía (rayos X).

Abstract

Living beings are exposed to various agents that damage DNA, which can cause an alteration at the molecular level causing disorder or diseases such as cancer. The damage caused in the DNA sequence is a very common process in the existence of a cell, it is also responsible for the appearance of mutations, which can cause uncontrolled growth or the death of the cell itself. Alterations in the DNA sequence can arise both from molecules and from endogenous mechanisms of cell metabolism, such as errors in the DNA replication process. In addition to this, they are a caused by environmental factors such as ultraviolet light, high energy radiation such as x- rays, here factors obstruct the process of DNA replication, transcription and translation, there may even be a lack of control during the process of cellular division.
