Metavirus
''Metavirus'' is a genus of viruses in the family ''Metaviridae''. They are retrotransposons that invade a eukaryotic host genome and may only replicate once the virus has infected the host. These genetic elements exist to infect and replicate in their host genome and are derived from ancestral elements unrelated from their host. ''Metavirus'' may use several different hosts for transmission, and has been found to be transmissible through ovule and pollen of some plants. ''Metavirus'' contains five families of the ''Ty3/Gypsy'' element with either one or two open-reading frames; these families are ''mdg1, mdg3, blastopia,'' ''412,'' and ''micropia''. Each of the five families contains either one or two open-reading frames, ''gag3'' and/or ''pol3''. There is evidence to support that amino acid deprivation in the elements host genome has frequently caused a frameshift towards the ''Ty3'' element. ''Metavirus'' corresponds with the ''Ogre/Tat'' gene lineage. Morphology Species of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metaviridae
''Metaviridae'' is a family of viruses which exist as Ty3-gypsy LTR retrotransposons in a eukaryotic host's genome. They are closely related to retroviruses: members of the family ''Metaviridae'' share many genomic elements with retroviruses, including length, organization, and genes themselves. This includes genes that encode reverse transcriptase, integrase, and capsid proteins. The reverse transcriptase and integrase proteins are needed for the retrotransposon activity of the virus. In some cases, virus-like particles can be formed from capsid proteins. Some assembled virus-like particles of members of the family ''Metaviridae'' can penetrate and infect previously uninfected cells. An example of this is the gypsy, a retroelement found in the ''Drosophila melanogaster'' genome. The ability to infect other cells is determined by the presence of the retroviral ''env'' genes which encode coat proteins. ''Metaviridae'' is a family of retrotransposons found in all eukaryotes known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RNA Reverse-transcribing Viruses
Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation and expression of genes. RNA and deoxyribonucleic acid ( DNA) are nucleic acids. Along with lipids, proteins, and carbohydrates, nucleic acids constitute one of the four major macromolecules essential for all known forms of life. Like DNA, RNA is assembled as a chain of nucleotides, but unlike DNA, RNA is found in nature as a single strand folded onto itself, rather than a paired double strand. Cellular organisms use messenger RNA (''mRNA'') to convey genetic information (using the nitrogenous bases of guanine, uracil, adenine, and cytosine, denoted by the letters G, U, A, and C) that directs synthesis of specific proteins. Many viruses encode their genetic information using an RNA genome. Some RNA molecules play an active role within cells by catalyzing biological reactions, controlling gene expression, or sensing and communicating responses to cellular signa ...
