The envelope structure of certain flu viruses and bacteriophages is based on icosahedral rotational symmetry.

The virus's capsid shields the nucleic acid from the outside world, and some viruses encase their capsids in a membrane envelope.

The majority of viruses have icosahedral or helical capsid forms, but some have complex virion architecture. To increase the size of the capsid, icosahedral viruses increase the number of structural units in each face. A 20-sided geometric shape called an icosahedron is made up of equilateral triangles on each of its 20 sides.

<u>Because icosahedral rotational symmetry makes it easier for viruses to grow and protect their genetic material, it allows them to infect and repeat their RNA on hosts more easily in the future</u>.
