Viruses are intracellular parasites. The penetration of viruses into the cell is based on receptor interaction mechanisms.
The surface area of the cell membrane to which the virus attaches is immersed in the cytoplasm and converted into a vacuole, which can merge with the nuclear membrane.
The infectious process begins when the viruses that enter the cell begin to multiply, i.e., the viral genome is reduced and the capsid is self-assembled. After the synthesis of a new virus nucleic acid molecule, it is dressed with viral proteins synthesized in the cytoplasm of the host cell – a capsid is formed.
The release of viral particles into the environment may be accompanied by cell destruction.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
