Compare autonomous and nonautonomous controlling elements in maize
What will be an ideal response?
Ans: Autonomous controlling elements contain genes encoding proteins that allow them to transpose. They transpose in a nonreplicative manner, so that their transposition out of an insertion site returns that site to its original sequence. Nonautonomous elements are derived from autonomous elements, with mutations in the protein-coding genes that prevent them from directing their own transposition. However, the presence of autonomous elements in the genome allows nonautonomous elements to transpose.
