  2. Negative-strand RNA virus - Wikipedia

    en.wikipedia.org/wiki/Negative-strand_RNA_virus

    Negative-strand RNA viruses (−ssRNA viruses) are a group of related viruses that have negative-sense, single-stranded genomes made of ribonucleic acid (RNA). They have genomes that act as complementary strands from which messenger RNA (mRNA) is synthesized by the viral enzyme RNA-dependent RNA polymerase (RdRp). During replication of the ...

  3. Sense (molecular biology) - Wikipedia

    en.wikipedia.org/wiki/Sense_(molecular_biology)

    The genome of an RNA virus can be said to be either positive-sense, also known as a "plus-strand", or negative-sense, also known as a "minus-strand". In most cases, the terms "sense" and "strand" are used interchangeably, making terms such as "positive-strand" equivalent to "positive-sense", and "plus-strand" equivalent to "plus-sense".

  4. Orthomyxoviridae - Wikipedia

    en.wikipedia.org/wiki/Orthomyxoviridae

    Viruses of the family Orthomyxoviridae contain six to eight segments of linear negative-sense single stranded RNA. They have a total genome length that is 10,000–14,600 nucleotides (nt). [7] The influenza A genome, for instance, has eight pieces of segmented negative-sense RNA (13.5 kilobases total). [8]

    In contrast, purified RNA of a negative-sense virus is not infectious by itself as it needs to be transcribed into positive-sense RNA; each virion can be transcribed to several positive-sense RNAs. Ambisense RNA viruses resemble negative-sense RNA viruses, except they translate genes from their negative and positive strands. [6]

  6. Human metapneumovirus - Wikipedia

    en.wikipedia.org/wiki/Human_metapneumovirus

    Human metapneumovirus (HMPV or hMPV) is a negative-sense single-stranded RNA virus of the family Pneumoviridae and is closely related to the Avian metapneumovirus (AMPV) subgroup C. It was isolated for the first time in 2001 in the Netherlands by using the RAP-PCR (RNA arbitrarily primed PCR ) technique for identification of unknown viruses ...

  7. Respiratory syncytial virus - Wikipedia

    en.wikipedia.org/wiki/Respiratory_syncytial_virus

    Respiratory syncytial virus (RSV), [a] also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a contagious virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. [2] Its name is derived from the large cells known as syncytia that form when infected cells fuse. [2] [3]
