Definition
Mutagens are agents, such as chemicals, radiation, or biological factors, that induce changes or alterations in the DNA sequence of an organism, potentially leading to mutations. These mutations can affect gene function and may contribute to various biological effects, including cancer and genetic disorders.
Summary
Mutagens are agents that cause changes in the DNA sequence, leading to mutations. These mutations can arise from various sources, including physical, chemical, and biological agents. Understanding mutagens is crucial as they play a significant role in genetic diversity, evolution, and the development of diseases such as cancer. The effects of mutations can be beneficial, harmful, or neutral, impacting an organism's survival and adaptation. Cells have evolved complex mechanisms to repair DNA damage caused by mutagens, ensuring genetic stability. This knowledge is essential in fields like medicine, where understanding mutagens can lead to better cancer treatments and prevention strategies. By studying mutagens, we gain insights into the fundamental processes of life and the ongoing evolution of species.
