Reverse transcriptase polymerase chain reactions can aid in the diagnosis of all of the following viral infections except -
Normally in transcription, there is the formation of RNA from DNA.


Obviously, as the name suggests, reverse transcriptase will cause transcription in reverse fashion i.e synthesis of DNA from RNA. Then fresh RNA is formed from DNA.


Amongst the given options, the only adenovirus is a DNA virus. All other are RNA viruses.


Reverse transcriptase induces the formation of DNA from RNA. so it can be used in the diagnosis of RNA viruses only.
Adenovirus
Astrovirus
Rotavirus
Poliovirus
