Does RNA serve as the genetic material of some plants and animals along with viruses?

Question

My teacher mentioned that some plants and animals have RNA as genetic material but did not substantiate his statement with examples. I'm wondering if it is so? I have searched the internet but have found no such information.

Answer 1

There are no animals or plants with RNA genomes. There was a mistaken belief in the 1920s that plant genetic material was RNA whereas animals had DNA, but this was finally disproved by JN Davidson in the 1940s.
