The 1000 Genomes Project (1KGP), taken place from January 2008 to 2015, was an international research effort to establish the most detailed catalogue of human genetic variation at the time. Scientists planned to sequence the genomes of at least one thousand anonymous healthy participants from a number of different ethnic groups within the ...
Genomoviridae is a family of single stranded DNA viruses that mainly infect fungi. [1] The genomes of this family are small (2.2–2.4 kilobases in length). The genomes are circular single-stranded DNA and encode rolling-circle replication initiation proteins (Rep) and unique capsid proteins.
Virosphere (virus diversity, virus world, global virosphere) was coined to refer to all those places in which viruses are found or which are affected by viruses. [1] [2] However, more recently virosphere has also been used to refer to the pool of viruses that occurs in all hosts and all environments, [3] as well as viruses associated with specific types of hosts (prokaryotic virosphere, [4 ...
The viruses have large, double-stranded DNA genomes (300 to >1000 kilobasepairs) that encode a large contingent of genes (of the order of 1000 genes). [ 3 ] [ 5 ] The best characterized giant viruses are the phylogenetically related mimivirus and megavirus , which belong to the family Mimiviridae (aka Megaviridae ), and are distinguished by ...
Most viruses have RNA genomes. Plant viruses tend to have single-stranded RNA genomes and bacteriophages tend to have double-stranded DNA genomes. [26]: 96–99 Viral genomes are circular, as in the polyomaviruses, or linear, as in the adenoviruses. The type of nucleic acid is irrelevant to the shape of the genome.
The EsV-1 phaeovirus is an exception with 231 protein encoding genes, which means it has one gene per approximately 1450 bp. In spite of the compact genomes typically found in viruses, Phycodnaviridae genomes have repetitive regions usually near the terminal ends and certain tandem repeats located throughout the genome. It is suggested that ...
Whole genomes. This level contains information about the virus species or isolate and its entire genomic sequence. Annotated genes. This level contains all the predicted ORFs (open reading frames) in a particular virus genome, together with their DNA and (translated) protein sequences. Ortholog groups (families).
The Marseilleviridae viruses have double stranded DNA genomes that are about 368 kilobases long. Members of the family can have about 457 open reading frames (ORFs) in its genome. The host organisms are amoebae. Once it infects, viral replication takes place in virus factories in the cytoplasm.
