Environmental factors can really affect DNA, which is important for making sure living things stay healthy. Let's break this down into simpler parts.
Radiation: When we get too much UV light from the sun, it can hurt our DNA. This type of damage can mess up how DNA works and stops it from making copies of itself correctly.
Temperature Changes: When temperatures get too high, DNA can start to fall apart. This makes it hard for DNA to keep its shape and affects how well it can copy itself or make proteins.
Pollutants: Bad chemicals, like heavy metals and certain pesticides, can change DNA. This can cause mutations that might lead to serious problems like cancer.
Endocrine Disruptors: These are substances that can throw off the way hormones work. They can affect how DNA operates, leading to problems in how genes are expressed.
Even though these environmental factors can cause serious issues, there are ways to help fix or lessen their effects:
DNA Repair Systems: Our cells have smart ways to fix some of the damage done to DNA. These include methods like base excision repair and nucleotide excision repair.
Environmental Management: We can reduce how much we expose ourselves to harmful substances. This can be done by creating stricter rules about chemicals and by promoting cleaner technologies.
Public Awareness and Education: Teaching people about how the environment affects DNA can help them make better choices in their lives. This can lead to healthier environments and better DNA health.
