A viral protein is both a component and a product of a virus. Viral proteins are grouped according to their functions, and groups of viral proteins include structural proteins, nonstructural proteins, regulatory proteins, and accessory proteins.[1] Viruses are non-living and do not have the means to reproduce on their own, instead depending on their host cell's resources in order to reproduce. Thus, viruses do not code for many of their own viral proteins, and instead use the host cell's machinery to produce the viral proteins they require for replication

The destruction of tissue by rapid freezing with substances such as liquid nitrogen is known as cryosurgery.
Liquid nitrogen is a chemical substance that has a boiling point of –320°F (–196°C). It finds its applications in a variety of things like, as a coolant, in medicines, in cryogenics, for transport, vacuum pumps, etc. Skin contact with the liquid nitrogen should be avoided as it can cause burns and even blisters.
Cryosurgery is the surgical procedure where an extremely cold liquid is used to freeze the damaged tissues of the body. It can be used to treat cancer. STDs like genital warts are also treated with this surgery.
