Epstein-Barr Virus (EBV)
Belong to the gammaherpesvirus subfamily of herpesviruses
Nucleocapsid 100 nm in diameter, with 162 capsomers
Membrane is derived by budding of immature particles through cell membrane and is required for infectivity.
Genome is a linear double stranded DNA molecule with 172 kbp
The viral genome does not normally integrate into the cellular DNA but forms circular episomes which reside in the nucleus.
The genome is large enough to code for 100 - 200 proteins but only a few have been identified.
