- A Introns removed during pre-mRNA splicing
- B Transposons (jumping genes)
- C Exons retained in the mature mRNA transcript
- D Promoters that recruit RNA polymerase to a gene
Correct answer: B. Transposons (jumping genes)
Explanation: Transposons (transposable elements/jumping genes) discovered by Barbara McClintock can move from one location to another in the genome.
