What destroys bacteria by denaturation of proteins?

UV radiation
Ethanol
Pressure sterilization
Dry heat

The correct answer is: Pressure sterilization

Pressure sterilization destroys bacteria by denaturation of proteins through high heat and pressure. While options A, B, and D all have antibacterial properties, they do not directly cause denaturation of proteins. UV radiation damages the DNA of bacteria rather than proteins, ethanol dissolves the bacterial cell membranes, and dry heat simply dehydrates and kills bacteria without targeting proteins specifically. Therefore, these options are incorrect in the context of the question.
