Question

Is reverse central dogma found in all viruses?

Answer 1

A virus is a tiny infectious agent that multiplies solely within a live host. Viruses infect all living things, including bacteria and archaea, from mammals and plants to microbes. Viruses are the most common form of microorganism and may be found in nearly every ecosystem on the planet. Virology is a subspecialty of microbiology that studies viruses.

Complete answer:
An explanation of the movement of genetic information inside a biological system is the basic process in molecular biology. Although this is not its original meaning, it is sometimes expressed as "DNA produces RNA, and RNA makes protein". This statement states that once "information" has been transferred into protein, it cannot be retrieved. More specifically, information may be transferred from nucleic acid to nucleic acid or from nucleic acid to protein, but not from protein to protein or from protein to nucleic acid. The exact determination of sequence, whether of bases in a nucleic acid or amino acid residues in a protein, is referred to as information.
A retrovirus is a kind of virus that changes the genome of the cell it infects by inserting a copy of its RNA genome into the DNA of the cell it infects. The virus utilises its own reverse transcriptase enzyme to generate DNA from its RNA genome once inside the host cell's cytoplasm, which is the opposite of the typical process (backwards). An integrase enzyme subsequently incorporates the new DNA into the host cell genome, transforming the retroviral DNA into a provirus. The host cell then treats the viral DNA as if it were its own, transcribing and translating the viral genes alongside the cell's own genes to produce the proteins needed to replicate the virus.
Reverse transcription is only seen in retroviruses. In their genome, they have RNA. The process of converting RNA to DNA is the polar opposite of core dogma. In 1970, reverse transcription was discovered by David Baltimore and Howard Temin.

Note:
There were no exceptions to the unidirectional and believed irreversible transfer of genetic information from DNA to RNA to protein in the early days of molecular biology. The "Central Dogma" was named after this unidirectional flow. When the replication of retroviruses was discovered, this Central Dogma had to be revised: The transcribing of RNA into DNA by a virus-coded polymerase, reversing the flow of genetic information, is a crucial stage in the retrovirus development cycle, thus the words "retroviruses" and "reverse transcriptase."
