Question

Quizplus · Accepted Answer

Retrotransposons are mobile genetic elements that transpose via an RNA intermediate. The yeast Ty element is a well-known retrotransposon that is capable of retrotransposition. The bacterial IS sequence, Drosophila P element, and maize activator (Ac) element do not use an RNA intermediate for transposition and are not retrotransposons.
