Definition Of:

RETROVIRUS

Bible DictionaryAids Glossary
a retrovirus -- such as HIV -- replicate using an enzyme (reverse transcriptase) to copy RNA into DNA. Most cells have DNA in their natural state and transcribe to RNA (ribonucleac acid) during replication. A retrovirus does things backwards -- RNA, not DNA, is its natural genetic state.
Bible DictionaryGlossary of HIV(AIDS)-Related Terms
A type of virus that, when not infecting a cell, stores its genetic information on a single-stranded RNA<!-- (see) --> molecule instead of the more usual double-stranded DNA<!-- (see) -->. HIV is an example of a retrovirus. After a retrovirus penetrates a cell, it constructs a DNA version of its genes using a special enzyme called reverse transcriptase<!-- (see) -->. This DNA then becomes part of the cell's genetic material.
Bible DictionaryHIV Vaccine Glossary
HIV and other viruses that carry their genetic material in the form of RNA rather than DNA and have the enzyme reverse transcriptase that can transcribe it into DNA. In most animals and plants, DNA is usually made into RNA, hence "retro" is used to indicate the opposite direction.
Bible DictionaryGlossary of HIV(AIDS) Terms
A strand of RNA (ribonucleic acid) surrounded by a protein shell. Retroviruses capable of infecting and causing disease in humans are relatively rare (and were only discovered in 1978). HIV is a retrovirus.
Bible DictionaryNCI Dictionary of Cancer Terms
A type of virus that has RNA instead of DNA as its geneticmaterial. It uses an enzyme called reverse transcriptase to become part of the host cells' DNA. This allows many copies of the virus to be made in the host cells. The virus that causes AIDS, the human immunodeficiency virus (HIV), is a type of retrovirus.
