Final answer:
The enzymatic activity encoded by a simple transposon depends on whether it is an autonomous or non-autonomous transposon.
Step-by-step explanation:
The enzymatic activity encoded by a simple transposon depends on whether it is an autonomous or non-autonomous transposon. Autonomous transposons have all the necessary genes and enzymes for transposition, including the specific enzymes required for mobility. Non-autonomous transposons, on the other hand, lack or cannot transcribe the genes for mobility enzymes, so they rely on the assistance of autonomous transposons.
For example, the maize Ac element is an autonomous Class II transposon that encodes all the structural and functional features necessary for transposition. In contrast, the maize Ds element is a non-autonomous transposon that lacks the genes for mobility enzymes and can only transpose with the help of the Ac element.
In summary, the enzymatic activity encoded by a simple transposon can vary depending on whether it is an autonomous or non-autonomous transposon.
