in the denaturation step of PCR. This resistance to high temperature allows for DNA polymerase to elongate DNA with a desired sequence of interest with the presence of dNTPs.

Feed additives

Enzymes are often added to animal feed to improve the health and growth of farmed animals, particularly chickens and pigs. The feed is typically treated with high pressure steam to kill bacteria such as Salmonella. Therefore the added enzymes (e.g. phytase and xylanase)
