Answer:
The answer is (E) Gene duplication from replicating transposable elements.
Explanation:
Gene duplication from crossing over or unequal crossing over can leads to appearance of new DNA sequences. Then, the new sequences create new genes. It can also find in many text books as a chromosome mutation.
From C. exon shuffling, it is also a way to make new genes in which different exons from different genes can be bought together, or the same exon is duplicated. Thus, these causes change the DNA sequences.
