What role do free radicals play in mutations?
Understand the Problem
The question is asking about the role of free radicals in causing mutations, focusing on how they interact with DNA. We need to analyze the options provided to identify which describes their role accurately.
Answer
Free radicals can damage DNA, causing mutations that increase disease risk.
Free radicals can damage DNA, which sometimes results in mutations. These mutations can increase the risk of diseases such as cancer and heart disease.
Answer for screen readers
Free radicals can damage DNA, which sometimes results in mutations. These mutations can increase the risk of diseases such as cancer and heart disease.
More Information
Free radicals are highly reactive molecules with unpaired electrons. While they play roles in cell signaling and homeostasis, excessive free radicals can lead to oxidative stress, which can damage cellular components like DNA. This damage can cause mutations, potentially contributing to aging and disease.
Tips
A common mistake is assuming all free radicals cause damage. Some play essential roles in immune response and cell signaling.
