Questions & Answers

Q: What was the focus of the 2015 Nobel Prize in Chemistry?

The Nobel Prize recognized Tomas Lindahl, Paul Modrich, and Aziz Sancar for their research on DNA repair mechanisms essential for genetic stability.

Q: How does DNA replication occur, and why is it crucial for cell division?

During cell division, DNA replicates to produce identical copies, ensuring each new cell receives the correct genetic information, vital for normal cellular functions.

Q: What are the different types of DNA damage, and how do repair mechanisms address them?

DNA can be damaged by various factors, such as chemical reactions or UV light, but specialized repair mechanisms remove and replace the damaged segments to maintain genetic integrity.

Q: Why is understanding DNA repair mechanisms important for preventing diseases like cancer?

DNA repair mechanisms play a crucial role in detecting and correcting mutations that could lead to cancer, highlighting the significance of studying these processes for human health.
