What diseases are caused by DNA replication?

What diseases are caused by DNA replication?

DNA damage. DNA is continually subjected to both exogenous and endogenous mutagenesis.

  • DNA repair.
  • Bloom’s syndrome.
  • Ataxia telangiectasia (Louis-Bar syndrome)
  • Fanconi’s anaemia.
  • Xeroderma pigmentosa, Cockayne’s syndrome, and trichothiodystrophy.
  • Conclusion.
  • How does virus replication cause disease?

    During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it. During uncoating, replication, and assembly, the viral DNA or RNA incorporates itself into the host cell’s genetic material and induces it to replicate the viral genome.

    What are some examples of DNA viruses?

    DNA virus: A virus in which the genetic material is DNA rather than RNA. The DNA may be either double- or single-stranded. Major groups of double-stranded DNA viruses (class I viruses) include the adenoviruses, the herpes viruses, and the poxviruses.

    What is a human infecting virus that has a DNA based genome?

    Most of these viral genes come from retroviruses, RNA viruses that insert DNA copies of their own genes into our genomes when they infect cells. HHV-6 is unique because it is the only known human DNA herpesvirus that integrates into the human genome and can be routinely inherited.

    How is Werner syndrome treated?

    Depending upon such factors, treatment methods may include surgery, use of certain anticancer drugs (chemotherapy), radiation therapy, and/or other measures. Genetic counseling is recommended for individuals with Werner syndrome and their families.

    Which are the virus diseases?

    Exanthematous viral disease

    • measles.
    • rubella.
    • chickenpox/shingles.
    • roseola.
    • smallpox.
    • fifth disease.
    • chikungunya virus infection.

    How do DNA viruses replicate?

    DNA viruses replicate their genomes using DNA polymerase enzymes and transcribe their mRNA using DNA-dependent RNA polymerase enzymes. Both (+) and (−) ssRNA viruses replicate and transcribe their genomes using RdRp enzymes (Fig. 3.1).

    What diseases are caused by RNA viruses?

    Human diseases causing RNA viruses include Orthomyxoviruses, Hepatitis C Virus (HCV), Ebola disease, SARS, influenza, polio measles and retrovirus including adult Human T-cell lymphotropic virus type 1 (HTLV-1) and human immunodeficiency virus (HIV).
