Consider Two Theoretical Transposable Elements in Yeast, a and B

question 55

Multiple Choice

Consider two theoretical transposable elements in yeast, A and B. Each contains an intron and each transposed to a new location in the yeast genome. Suppose you then examine the transposons for the presence of the intron. In the new locations, you find that A has no intron but B does. From these facts, what can you conclude about the mechanisms of transposition for the two transposable elements?

• A) B probably makes a transposase.
• B) A probably has inverted repeats at each end of the element.
• C) B probably uses RNA as an intermediate in the transposition event.
• D) B probably makes a reverse transcriptase.
• E) A probably doesn't create a duplication of the host genome target sequence.
