Quizplus · Accepted Answer

Copy number variants involve the duplication or deletion of relatively long stretches of DNA, often including protein-coding genes. Single nucleotide polymorphisms (B) involve variation at a single nucleotide position in the DNA sequence. Short tandem repeats (C) involve variation in the number of repeats of a short DNA sequence. Transposable elements (D) involve the movement of DNA sequences within the genome. Exon shuffling (E) involves the rearrangement of exons within genes.
