GENERAL MORPHOLOGY Viruses may be classified into several morphological types on the basis of their capsid architecture as revealed by electron microscopy and a technique called X-ray crystallography

A. Some viruses. such as tobacco mosaic virus, have a helical symmetry with the capsid surrounding an RNA genome B, Many viruses that infect bacteria, such as the T-even bacteriophage, have a complex LR&A capsid with DNA contained within the head structure C. Some animal viruses such as adenovirus have isometric symmetry and a dna genome D, others, such as coronavirus(冠状病毒) have complex capsids and an envelope with protruding proteins surrounding an RNa genome
