Bacteria and archaea that grow at extreme pH or temperature possess which feature to protect their DNA from denaturation?

Question

Quizplus · Accepted Answer

DNA-binding proteins are proteins that bind to DNA and play a role in protecting it from damage. Bacteria and archaea that grow at extreme pH or temperature often possess DNA-binding proteins that help to protect their DNA from denaturation. These proteins may stabilize the DNA molecule by preventing it from becoming over-coiled or by preventing single-stranded regions from forming. Overall, DNA-binding proteins help to protect the integrity of the genetic material, allowing these organisms to survive in extreme environments.
