Thermostable DNA polymerase

Thermostable DNA polymerase is an enzyme that can copy DNA molecules repeatedly at high temperatures without losing activity. It's essential in the process called PCR (Polymerase Chain Reaction), where DNA is rapidly heated and cooled to make millions of copies of a specific DNA segment. This enzyme can withstand the high heat needed to separate DNA strands, unlike regular enzymes that would break down. Its stability at high temperatures makes DNA copying faster, more efficient, and practical for scientific, medical, and forensic applications.
