APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Retroviruses are viruses with RNA as genetic material. They belong to the family Retroviridae of Retroviruses. Once it has infected a cell, it converts its RNA into DNA by reverse transcription. This viral DNA is then inserted into the DNA of the host cell where it starts replicating.

Detailed explanation-2: -RNA viruses, such as retroviruses, use the enzyme to reverse-transcribe their RNA genomes into DNA, which is then integrated into the host genome and replicated along with it.

Detailed explanation-3: -Reverse transcriptases (RTs) play a major role in the replication of Retroviridae, Metaviridae, Pseudoviridae, Hepadnaviridae and Caulimoviridae.

Detailed explanation-4: –Retroviruses use the enzyme reverse transcriptase to transcribe a copy of DNA from their own RNA.

Detailed explanation-5: -DNA integration is a unique enzymatic process shared by all retroviruses and retrotransposons. During integration, double-stranded linear viral DNA is inserted into the host genome in a process catalyzed by the virus-encoded integrase (IN).
