There are a number of additional viruses that have not been classified to date. These are the parvovirus like viruses. These viruses has linear single stranded DNA genomes but unlike the parvoviruses the genome is bipartate. This group includes the Ina-flacherie virus (Bombyx mori parvo-like virus), Lymphoidal parvo-like virus, Hepatopancreatic parvo-like virus and Bombyx mori densovirus type 2. They have only been isolated from invertebrates to date and their relationships to other groups has not yet been established.
It is called a chromatid.Two chromatids are hold by centromere.
Bacteria, or single celled organisms
The virus has DNA as its genetic material. More interesting, the DNA is single-stranded. "Parvo" is short for "parvovirus" and usually "canine parvovirus type 2."
DNA is a double-stranded nucleic acid.
The new name is Aggregatibacter. Desrin Conteh (Dental Therapist/Hygienist)
The word is bacteria. It is a single celled organism.

Bacteria are one-celled. Monera means having one cell.
Major groups of viruses are distinguished first by their nucleic acid content as either RNA or DNA viruses. Subsequent subdivisions are based largely on other properties of nucleic acids. The RNA viruses can be single-stranded (ssRNA) or double-stranded (dsRNA), although most are single-stranded. Because most eukaryotic cells do not have the enzymes to copy viral RNA molecules, the RNA viruses must either carry the enzymes or have the genes for those enzymes as part of their genes. Like RNA viruses, DNA viruses can also occur in single-stranded or double-stranded form.

in humans there is one strand of RNA, hence the name single-stranded RNA. However, in some viruses (such as HIV), there are double-stranded RNA made by the enzyme transcriptase.
Life consists of three domains; Archaea, Bacteria and Eukarya. Of these domains, Archaea and Bacteria consist exclusively of single celled organisms. Additionally, one of the four kingdoms of Eukarya, i.e. Protista, consists of single celled organisms.So single celled organisms could be referred to as Archaea, Bacteria and Protista.
"saturated"
Saprophytic bacteria belong to various taxonomic groups, including Actinobacteria, Firmicutes, and Proteobacteria. There is no single scientific name that encompasses all saprophytic bacteria as they encompass a diverse range of bacterial species.
