What is virus made of

Mark as done. Next: 2. How do viruses replicate? Viruses are simple, and are made up of up to three constitutive elements: A genome, made up of nucleic acids that can be DNA like humans or RNA. The genome is protected by a protein coat, called a capsid. The capsid proteins capsomeres assemble around the viral genome in different arrangements, termed either helical e.

Some viruses possess an outer lipid envelope, which is derived from the host cell and can take many forms. Enveloped viruses are more susceptible to destruction of the lipid through the use of soap or alcoholic hand-gels, than viruses without lipid envelopes. The bulbous projections seen on the outside of the coronavirus are spike proteins red-orange. This fringe of proteins gives the virus its crown-like appearance under the microscope, from which the Latin name corona is derived.

The spike proteins act as grappling hooks that allow the virus to latch onto host cells and crack them open for infection. Baron Ed. University of Texas Medical Branch. Holmes, E.
