Final answer:
AluI is a type of short interspersed element (SINE) or retrotransposon found in the human genome, known to facilitate genomic diversity and exon shuffling.
Step-by-step explanation:
AluI is an example of a short interspersed element (SINE), which is a type of transposable element commonly found in the human genome. These elements are also known as retrotransposons and have a significant role in genomic diversity and evolution. Specifically, the Alu elements can stimulate exon shuffling and unequal recombination through their presence in introns where they can facilitate the movement of exons between unrelated genes to share domains and specific functions.
Furthermore, the presence of transposable elements like AluI across various species supports the theory of their early evolution and hints at horizontal DNA transfer in their distribution.
