Does viruses have complex structures?

Viruses did not evolve first, they found. Instead, viruses and bacteria both descended from an ancient cellular life form. But while – like humans – bacteria evolved to become more complex, viruses became simpler. Today, viruses are so small and simple, they can't even replicate on their own.

While some have symmetrical shapes, viruses with asymmetrical structures are referred to as “complex. ” These viruses possess a capsid that is neither purely helical nor purely icosahedral, and may possess extra structures such as protein tails or a complex outer walls.

Explanation:

Viruses consist of nucleic acid -- either RNA or DNA -- surrounded by a protective shell, known as the capsid. The job description of every virus is simple: enter a living cell, hijack its metabolic machinery and make progeny. All viruses contain nucleic acid, either DNA or RNA (but not both), and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its infective form, outside the cell, a virus particle is called a virion.
