What Size Is A Virus

» How big are viruses?

Details: The interplay between the virus size and the genome length can be captured via the packing ratio which is the percent fraction of the capsid volume taken by viral DNA. For phage lambda it can be calculated to be about 40% whereas for HIV it is more than 10 times lower (BNID 111591).
