type 1 has a genome of 1,759 nucleotides and a capsid diameter of 17 nm. As a whole, the viral family geminiviridae is about 30 nm in length. However, the two capsids making up the virus are fused; divided, the capsids would be 15 nm in length. Other environmentally characterized ssDNA viruses such as CRESS DNA viruses, among others, can have genomes that are considerably less than 2,000 nucleotides.
