Question

Quizplus · Accepted Answer

Transposons are mobile genetic elements that can "jump" from one location to another within a genome. They are believed to have played a role in the evolution of viruses, as they share some similarities in their ability to move between different hosts and incorporate themselves into new genetic material. mRNA, exons, and introns are all components of eukaryotic gene expression, but are not directly related to the evolution of viruses. Mitochondrial DNA is found only in eukaryotic cells and is not believed to have played a role in the evolution of viruses.
