To analyse: The origin of viruses and the fact that viruses can so easily enter and get uncoated inside human cells. Introduction: Viruses are unique microorganisms that don’t show any signs of life until they come in contact with their specific hosts. Once this contact happens, viruses enter their host cells and use the cellular and genetic machinery of the host cell to multiply. Once their multiplication cycle is over, they are released from the host cell and infect new host cells.

To analyse:

The origin of viruses and the fact that viruses can so easily enter and get uncoated inside human cells.

Introduction:

Viruses are unique microorganisms that don’t show any signs of life until they come in contact with their specific hosts. Once this contact happens, viruses enter their host cells and use the cellular and genetic machinery of the host cell to multiply. Once their multiplication cycle is over, they are released from the host cell and infect new host cells.

Expert Solution & Answer

Explanation of Solution

Since viruses are very simple in structure, comprising of only nucleic acid and protein coat, it may be postulated that viruses were probably the first microorganisms on Earth, though not living. It is likely that viruses were the intermediate step in evolution from macromolecules to living cells.

This is clearly evident in the ease with which viruses are able to enter inside their host cells. The presence of corresponding receptors on the surface of the host cell and the machinery to uncoat viral particles clearly indicate the evolutionary connection between viruses and living cells.

Conclusion

Viruses and living cells seem to be evolutionarily connected.
