''Anelloviridae'' is a family Family (from la, familia) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its ... of viruses. They are classified as vertebrate viruses and have a non-enveloped capsid, which is round with isometric, icosahedral symmetry and has a triangulation number of 3. The name is derived from Italian ''anello'' 'ring', referring to the circular genome of anelloviruses. Genome The genome is not segmented and contains a single molecule of cccDNA, circular, negative-sense, single-stranded DNA. The complete genome is 3000–4000 nucleotides long. They also contain a non-coding region with one to two 80–110 nt sequences that contain high GC content, forming a secondary structure of stems and loops. The genome has Open reading frame, ORFs and a high degree of genetic diversity. Although the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
