Ovalbumin is the component of egg white which is responsible for foam formation.
Ovalbumin is the main protein component of the egg white and it is responsible for creating the foam structure when the egg whites are beaten. The physical stress caused by beating the egg white, causes the protein ovalbumin to denature and unfold. This denaturation, along with the mixing of air in the egg white, causes the formation of foam.
The best answer is A.
The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.
The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
