Virus shell

The viral envelope is a protein structure that surrounds the nucleic acid of the virions or nucleocapsnds. The shell may contain lipids and carbohydrates, which protect the virus from environmental influences and help it penetrate host cells.

The virus shell consists of several layers, each of which performs its own function. The outer layer is called the supercapsid and consists of lipids and carbohydrates that provide protection from external influences. The inner layer is called the capsid and contains the nucleic acid of the virus. The capsid protects the nucleic acid from the external environment and helps the virus penetrate the host cell.

Viruses have an envelope, thanks to which they can penetrate cells and multiply. The shell protects the virus from the action of antibodies and other defense mechanisms of the body. However, the shell can be destroyed by special drugs called antiviruses.

In conclusion, the viral envelope is an important part of its structure and plays an important role in protecting the virus from the external environment and entry into cells. Knowledge of the structure and function of the virus envelope can help in the development of new methods for treating and preventing viral infections.

Greetings, dear readers! In this article we will talk about the shell of viruses and what it is.

Viruses are tiny particles that can invade the cells of other organisms and use them to reproduce. In itself, only one such particle of viruses does not pose a threat - it is devoid of many features and properties that are characteristic of living beings. What makes us aware that viruses have entered cellular tissues with their help is their shell, which in appearance resembles anything from the flu to chickenpox. The virus shell is a protein structure consisting of many proteins, which serves to attach the nucleic acid to the host DNA, or RNA (in the case of protozoa, viruses), thereby preventing its further reproduction and causing destabilization of the cell.
