Quizplus · Accepted Answer

The fact that this element uses an RNA intermediate and is both transcribed and translated indicates that it is a retrotransposon. The only retrotransposons listed as choices are LINEs, which can be several kilobases long and are found in multiple copies throughout the genome. RNA transposons are also retrotransposons, but they are typically smaller and found in fewer copies. DNA transposons do not use an RNA intermediate for transposition. SINEs (short interspersed nuclear elements) are also retrotransposons, but they are shorter (around 300 base pairs) and typically found in higher copy numbers than the described element. Short tandem repeats are repetitive sequences of 2-6 nucleotides and are not transposons.
