Middle of paper
.... mosiac, adenovirus, influenza virus, and
t-even bacteriophage are each examples of a different virus structure. Each
individual protein subunit composing the capsid is a capsomere.
The tobacco mosiac virus has a helical capsoid and is rod shaped. The
adenovirus is polyhedral and has a protein spike at each vertex. The influenza
virus is made of a flexible, helecal capsid. It has an outer membranous
enevelope that is covered with glycoprotein spikes. The T-even bacteriophage
