A class of viruses whose genetic material is RNA rather than DNA and produces an enzyme known as reverse transcriptase Because retroviruses make this enzyme, they can transform their RNA into DNA, which can be permanently integrated into the DNA of the host cells
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
Family of viruses to which HIV belongs that are distinguished by their use of RNA It shares a common strategy for replicating that depends on an enzyme known as reverse transcriptase Retroviruses contain genetic information consisting of RNA which must first be copied by reverse transcriptase into a DNA copy during the early stages of the viral life cycle The DNA copy of the retrovirus then integrates into the chromosomes of the host cell and produces the requisite RNA and protein constituents of additional virus particles
A type of virus that, when not infecting a cell, stores its genetic information on a single-stranded RNA molecule instead of the more usual double-stranded DNA 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, reverse transcriptase This DNA then becomes part of the cell's genetic material
a virus of a type that includes some cancer viruses and the AIDS virus, but that also has a quality that makes it useful for genetic engineering. Any of a group of viruses that, unlike most other viruses and all cellular organisms, carry their genetic blueprint in the form of RNA. Retroviruses are responsible for some cancers and viral infections of animals, and they cause at least one type of human cancer. The retrovirus HIV is the cause of AIDS in humans. The name signifies that they use RNA to synthesize DNA, the reverse of the usual cell process. This process makes it possible for genetic material from a retrovirus to enter and become a permanent part of the genes of an infected cell
A family of RNA viruses that have the unique characteristic of producing an enzyme that makes a DNA copy of its genetic informationfrom an RNA template (the opposite of what normally takes place) The most widely recognized of these viruses is HIV, the causative agent in AIDS Another virus from this family (HTLV-1) has been associated with T cell leukemia Initial reports of an association of an HTLV-II-like retrovirus with CFS could not be confirmed in subsequent studies
HIV and other viruses that carry their genetic material in the form of RNA and that have the enzyme reverse transcriptase Like all viruses, HIV can replicate only inside cells, commandeering the cell's machinery to reproduce Like other retroviruses, HIV uses the enzyme called reverse transcriptase to convert its RNA into DNA, which is then integrated into the host cell DNA See also DNA; Reverse Transcriptase; Ribonucleic Acid
A virus that, when not infecting a cell, stores its genetic information on a single-stranded RNA molecule instead of the more usual double-stranded DNA HIV is an example After a retrovirus penetrates a cell, it constructs a DNA version of its genes using reverse transcriptase, an enzyme The DNA then becomes part of the cells genetic material
Also called a anti-antivirus virus, this is a virus that attacks, disables, or avoids infecting specific antivirus software It's just one of many methods used by virus authors to avoid detection by antivirus software
a family of viruses that can be a potent cause of diseases such as HIV, but when modified, may serve as a useful tool to molecular biologists based on a unique ability to deliver foreign genes into cells
a class of enveloped viruses that have their genetic material in the form of RNA and use reverse transcriptase to translate their RNA into DNA The retrovirus family includes oncoviruses (e g , HTLV-1) and lentiviruses (e g , HIV-1, HIV-2)
A family of viruses composed of RNA Once in a host cell they can use reverse transcriptase to perform a "backwards" conversion of RNA to DNA This family of viruses can cause leukemia in animals Three forms have been associated with human disease The two most important are the human immunodeficiency virus, which causes AIDS, and the human T lymphocytotropic virus 1, which causes an acute lymphoblastic leukemia /lymphoma syndrome in adults in certain geographic areas
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
{i} virus containing a single strand of RNA which is translated into DNA and inserted into a host cell at the time of infection (many viruses that cause cancer and the AIDS virus are retroviruses)
Any of a family of RNA viruses containing reverse transcriptase in the virion Retroviruses proliferate by a process that is the reverse of normal viruses Reverse transcriptase enables the virus to convert viral RNA into DNA This reverses the normal process of transcription where DNA is converted into RNA
A family of RNA viruses that have the unique characteristic of producing an enzyme that makes a DNA copy of its genetic information from an RNA template (the opposite of what normally takes place) The most widely recognized of these viruses is HIV, the causative agent in AIDS Another virus from this family (HTLV-1) has been associated with T cell leukemia Initial reports of an association of an HTLV-II-like retrovirus with CFS could not be confirmed in subsequent studies Top
A virus that has RNA as its genetic material When introduced into a host cell, it is used as a template to produce viral DNA, which leads to the formation of more, identical viruses
