How do transposable elements and short tandem repeats (STRs) differ?
A) STRs occur within exons; transposable elements occur within introns.
B) STRs occur within introns; transposable elements occur within exons.
C) STRs make up only a small percentage of a given genome while transposable elements often make up larger parts of a given genome.
D) The repeated unit in STRs is much larger than the repeated unit of transposable elements.

Quizplus · Accepted Answer

Short tandem repeats (STRs) are short sequences of DNA that are repeated in a tandem array. While they can be used for genetic analysis, they make up only a small percentage of a genome. Transposable elements, on the other hand, can make up larger parts of a genome as they are able to move around within the genome.

Therefore, choice C is the correct answer as it correctly identifies this difference between the two types of genetic elements.
