Delve deeper into the structures of the virus using the following virus diagrams that you can use as a reference. These diagrams illustrate the structures of a virus with the labels and one diagram without the labels for evaluation. Explore the following diagrams below and just click on an image of the diagram to enlarge and download!
Viruses vary in their structure. A virus particle consists of DNA or RNA within a protective protein coat called a capsid. The shape of the capsid may vary from one type of virus to another. The capsid is made from the proteins that are encoded by viral genes within their genome. It is made up of many morphological units, called capsomeres. Can you see the capsid on the virus diagram provided below?
In its infective form, outside the cell, a virus particle is called a virion. Each virion contains at least one unique protein synthesized by specific genes in its nucleic acid. While the double-stranded DNA is responsible for this in prokaryotic and eukaryotic cells, only a few groups of viruses use DNA. Most viruses maintain all their genetic information with the single-stranded RNA.
Many types of virus have a glycoprotein envelope surrounding the nucleocapsid as you can see on the diagram. The diagrams above are provided as a reference or study aid and one unlabeled version for evaluation purpose, all printable! Check back soon for more educational diagrams!
