what is a retrovirus in biology

Retroviruses are a diverse family of animal viruses that contain RNA as their genetic material but produce a double-stranded DNA copy of their genome upon infection. A retrovirus is a virus that uses RNA as its genetic material. When a retrovirus infects a cell, it makes a DNA copy of its genome that is inserted into the DNA of the host cell. There are a variety of different retroviruses that cause human diseases such as some forms of cancer and AIDS. Feb 22,  · Retrovirus: A virus that is composed not of DNA but of RNA. Retroviruses have an enzyme, called reverse transcriptase, that gives them the unique property of transcribing their RNA into DNA after entering a cell. The retroviral DNA can then integrate into the chromosomal DNA of the host cell, to be expressed there.

Combination of several typically three or four antiretroviral drugs is known as highly active anti-retroviral therapy HAART. The family Retroviridae was previously divided into three subfamilies OncovirinaeLentivirinaeand Spumavirinaebut are now divided into two: Orthoretrovirinae and Spumaretrovirinae.

Co-authors Due to the functional copy of env gene retroviruses are distinct from retroelements. What is a retrovirus in biology copy of the DNA genome gets into the host genome inside the nucleus via an enzyme called integrase.

And so using the integrating ability of a retrovirus, you can actually take something that could ordinarily harm people and check this out it into something that can be used as a therapeutic vehicle to make them better. The majority of the viruses have either DNA or RNA as their genetic component, and then the nucleic acid might be double- or single-stranded. Namespaces Article Talk. ISBN Thus, 5' terminal has the extra U3 sequence, while the other terminal has the U5 sequence. Horizon Scientific. Retroviruses have undergone an explosion in the last four decades.

The circular, double-stranded viral genome is approximately 8-kb in length. However, many endogenous retroviruses play important roles in host biology, such as control of gene transcription, cell fusion during placental development in the course of the germination of an embryoand resistance to exogenous retroviral retrovirys. After this, the novice DNA is incorporated into the genome of the host cell through an integrase enzyme. As a result, cells such as neurons are very resistant to infection and transduction by retroviruses.
