retrovirus
Noun: A type of virus that uses RNA as its genetic material. It contains an enzyme called reverse transcriptase, which allows it to convert its RNA into DNA. This DNA is then integrated into the genome of the host cell it infects.
The term is used specifically in biology, virology, and medicine to describe this distinct family of viruses. * HIV is a well-known retrovirus that causes AIDS. * Scientists study the replication cycle of a retrovirus to develop new treatments. * The discovery of reverse transcriptase was crucial for identifying retroviruses.
- As a modifier: The term is frequently used attributively (like an adjective) to describe related concepts.
- Retrovirus research has led to important medical advances.
- They studied the retrovirus genome.
- Provirus: This is a key related concept. It refers to the DNA form of the retrovirus that has been integrated into the host cell's chromosome.
- Retroviral (adjective): Pertaining to or caused by a retrovirus.
- Retroviral infections require specific types of antiretroviral drugs.
- Retroviridae (noun): The formal taxonomic family name for retroviruses.
- RNA virus (Note: This is a broader category; all retroviruses are RNA viruses, but not all RNA viruses are retroviruses. The key distinguishing feature is the use of reverse transcription.)
Given the technical nature of the word, it is not associated with phrasal verbs or idioms. Key related scientific terms include: * Reverse Transcriptase: The defining enzyme of a retrovirus. * Provirus: The integrated viral DNA. * Host Cell: The cell infected by the virus. * Antiretroviral: A drug used to treat retroviral infections.
- any of a group of viruses that contain two single-strand linear RNA molecules per virion and reverse transcriptase (RNA to DNA); the virus transcribes its RNA into a cDNA provirus that is then incorporated into the host cell
