  2. DNA virus - Wikipedia

    en.wikipedia.org/wiki/DNA_virus

    Orthopoxvirus particles. A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase.They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong ...

  4. Virus - Wikipedia

    en.wikipedia.org/wiki/Virus

    The genetic material within virus particles, and the method by which the material is replicated, varies considerably between different types of viruses. DNA viruses The genome replication of most DNA viruses takes place in the cell's nucleus. If the cell has the appropriate receptor on its surface, these viruses enter the cell either by direct ...

    en.wikipedia.org/wiki/Human_papillomavirus_infection

    Although HPV16 is a DNA virus, there are signs of recombination among the different lineages. [ 114 ] [ 116 ] Based on an analysis of more than 3600 genomes, between 0.3 and 1.2% of them could be recombinant. [ 114 ]

  6. Introduction to viruses - Wikipedia

    en.wikipedia.org/wiki/Introduction_to_viruses

    The genes of viruses are made from DNA (deoxyribonucleic acid) and, in many viruses, RNA (ribonucleic acid). The biological information contained in an organism is encoded in its DNA or RNA. Most organisms use DNA, but many viruses have RNA as their genetic material. The DNA or RNA of viruses consists of either a single strand or a double helix ...

  7. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...

  8. Viral eukaryogenesis - Wikipedia

    en.wikipedia.org/wiki/Viral_eukaryogenesis

    It is thus possible that viruses were involved in the creation of Earth's first cells. [8] The eukaryotic nucleus contains linear DNA with specialized end sequences, like that of viruses (and in contrast to bacterial genomes, which have a circular topology); it uses mRNA capping, and separates transcription from translation. Eukaryotic nuclei ...

  9. Poxviridae - Wikipedia

    en.wikipedia.org/wiki/Poxviridae

    The replication of poxvirus is unusual for a virus with double-stranded DNA genome because it occurs in the cytoplasm, [15] although this is typical of other large DNA viruses. [16] Poxvirus encodes its own machinery for genome transcription, a DNA dependent RNA polymerase, [17] which makes replication in the cytoplasm possible. Most double ...
