Mobile DNA elements likely contributed to the evolution of higher organisms by the
A)generation of gene families by gene duplication.
B)creation of new genes by exon shuffling.
C)formation of more complex regulatory regions.
D)all of the above

Question

Quizplus · Accepted Answer

Mobile DNA elements, such as transposons and retrotransposons, have been implicated in all three of the listed mechanisms for contributing to the evolution of higher organisms. They can generate gene families through gene duplication events, create new genes through exon shuffling, and form more complex regulatory regions by inserting or altering regulatory sequences. Therefore, the best choice is D, all of the above.
