[Campbell Biology P.508] Which of the following statements about the consequences of transpo... | Practice Question
Which of the following statements about the consequences of transposable element insertion, as described in the text, is TRUE ?
A: A transposable element 'jumping' into an intron will always prevent the production of a normal transcript.
B: Insertion of a transposable element into a protein-coding sequence will typically lead to increased protein production.
C: Transposition into a regulatory sequence can lead to either increased or decreased production of one or more proteins.
D: The insertion of an exon into an intron by transposition always results in a lethal mutation.
E: Transposable elements most often produce beneficial heritable changes.
Explanation
The text explicitly states: 'If a transposable element inserts within a regulatory sequence, the transposition may lead to increased or decreased production of one or more proteins.' This directly matches option C.
