Definition of retrovirus in English:

retrovirus

noun

Biology
  • Any of a group of RNA viruses that insert a DNA copy of their genome into the host cell in order to replicate, e.g., HIV.

    • ‘HIV is an RNA virus (ie, it carries its genetic code in the form of RNA) and falls under the family of retroviruses.’
    • ‘As a vehicle for gene therapy, the retrovirus is modified so that it cannot produce infectious virus after entering the cell.’
    • ‘I'm not talking about a vaccine, which most scientists consider a pipe dream against a diverse and constantly mutating retrovirus like HIV.’
    • ‘Thus far, adenoviruses and retroviruses are the two families of viruses that have been used in the majority of clinical trials.’
    • ‘All retroviruses are similar, and our genome is full of dormant retroviruses - over 2 percent of the genome is retroviral.’
