Pandoravirus Dulcis

	Pandoravirus Dulcis ''Pandoravirus dulcis'' is an egg-shaped virus of genus ''Pandoravirus'', that was discovered in a shallow lake at La Trobe University La Trobe University is a public research university based in Melbourne, Victoria, Australia. Its main campus is located in the suburb of Bundoora. The university was established in 1964, becoming the third university in the state of Victoria a ..., Melbourne, Australia in 2013. The virus contains around 1.9 million DNA bases and about 1500 genes. It infects amoeba living in pond water. Along with '' Pandoravirus salinus'', and around one micrometre in size, it is one of the largest viruses ever identified.

picture info	Nucleocytoplasmic Large DNA Viruses ''Nucleocytoviricota'' is a phylum of viruses. Members of the phylum are also known as the nucleocytoplasmic large DNA viruses (NCLDV), which serves as the basis of the name of the phylum with the suffix - for virus phylum. These viruses are referred to as nucleocytoplasmic because they are often able to replicate in both the host's cell nucleus and cytoplasm. The phylum is notable for containing the giant viruses. There are nine families of NCLDVs that all share certain genomic and structural characteristics; however, it is uncertain whether the similarities of the different families of this group have a common viral ancestor. One feature of this group is a large genome and the presence of many genes involved in DNA repair, DNA replication, transcription, and translation. Typically, viruses with smaller genomes do not contain genes for these processes. Most of the viruses in this family also replicate in both the host's nucleus and cytoplasm, thus the name nucleocytoplasmic. Th ...

	Pandoraviridae ''Pandoraviridae'' is a family of double-stranded DNA viruses that infect amoebae. There is only one genus in this family: ''Pandoravirus''. Several species in this genus have been described, including ''Pandoravirus dulcis'', '' Pandoravirus salinus'' and ''Pandoravirus yedoma''. History The viruses were discovered in 2013. Description The viruses in this family are the second largest known virus (~1 micrometer) in capsid length, after ''Pithovirus'' (1.5 micrometer). ''Pandoravirus'' has the largest viral genome known, containing double-stranded DNA of 1.9 to 2.5 megabase A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both D ... pairs. Evolution These viruses appear to be related to the phycodnaviruses.

	Pandoravirus ''Pandoravirus'' is a genus of giant virus, first discovered in 2013. It is the second largest in physical size of any known viral genus. Pandoraviruses have double stranded DNA genomes, with the largest genome size (2.5 million base pairs) of any known viral genus. Discovery The discovery of Pandoraviruses by a team of French scientists, led by husband and wife Jean-Michel Claverie and Chantal Abergel, was announced in a report in the journal ''Science'' in July 2013. Other scientists had previously observed the pandoravirus particles, but owing to their enormous size they were not expected to be viruses. Patrick Scheid, a parasitologist from the Central Institute of the Bundeswehr Medical Service in Koblenz, Germany, found one in 2008, in an amoeba living in the contact lens of a woman with keratitis. Its development within the amoebal host was documented extensively. Unlike in other cases with such giant viruses, the large particles within ''Acanthamoeba'' were not mistak ...

picture info	2013 In Science A number of significant scientific events occurred in 2013, including the discovery of numerous Earthlike exoplanets, the development of viable lab-grown ears, teeth, livers and blood vessels, and the atmospheric entry of the most destructive meteor since 1908. The year also saw successful new treatments for diseases such as HIV, Usher syndrome and leukodystrophy, and a major expansion in the use and capabilities of technologies such as 3D printing and autonomous cars. The United Nations designated 2013 the International Year of Water Cooperation. Events, discoveries and inventions January 2 January A study by Caltech astronomers reports that the Milky Way Galaxy contains at least one planet per star, resulting in approximately 100–400 billion exoplanets. The study, based on planets orbiting the star Kepler-32, suggests that planetary systems may be the norm around stars in our galaxy.
