Answer:

Viral genetic material is packaged inside protein structures called capsids. Viruses are divided into two groups: enveloped viruses are surrounded by an outer lipid membrane; nonenveloped viruses lack this membrane. Where present, the envelope contains the viral proteins, which mediate binding to host cells.
