Question

why can't a virus have both RNA and DNA ??? please explain in simple language .​

Answer 1

If a virus has RNA, it should have reverse transcriptase. If it has DNA, it should have DNA transcriptase. If it has both RNA and DNA, it must have both reverse transcriptase and DNA transcriptase. This makes transcription and propagation of virus a complicated process.

So it doesn't have both DNA and RNA.

Answer 2

Answer:

Viruses are an unusual exception. Admittedly, many biologists don't consider viruses to be a form of "life" since they can't reproduce on their own. While many viruses do have DNA genomes, others like HIV and the flu have genomes made from RNA instead. ... RNA includes a chemical unit not found in DNA called uracil.
