Final answer:
False. Despite its stability, DNA is not indestructible and can be damaged by various environmental factors. (Option 2)
Step-by-step explanation:
While DNA is stable under normal conditions, it is not indestructible. Various factors, such as exposure to ultraviolet (UV) radiation, certain chemicals, and mechanical stress, can cause damage to the DNA molecule. UV radiation, for instance, can induce the formation of thymine dimers, leading to mutations. Additionally, oxidative stress and environmental toxins can contribute to DNA damage. Although cells have repair mechanisms to fix some of these damages, they are not infallible, and unrepaired or misrepaired DNA can lead to genetic mutations and potentially cell death. Therefore, while DNA is remarkably stable, it is not immune to damage, and its integrity relies on the cellular repair processes.
DNA is not indestructible, and its stability can be compromised by various environmental factors, emphasizing the importance of cellular repair mechanisms in maintaining genetic integrity.
