Which of the following is a key difference between replicative and non-replicative transposition?
a. In non-replicative transposition, the gene is deleted from the genome, and in replicative transposition the original copy of the gene is inverted.
b. In non-replicative transposition, the transposition event occurs during mRNA processing, and in replicative transposition the transposition event is stimulated by RNA polymerase.
c. In non-replicative transposition, the gene is deleted from its original location, and in replicative transposition one copy of the gene always remains at the original site.
d. In non-replicative transposition, multiple copies of the gene are found, and in replicative transposition only one copy of the gene remains.

Which of the following statements correctly describes a DNA transposon? Flanking direct repeats are generated when a transposable element inserts into DNA. Transposable elements are mobile DNA sequences. A new copy of a transposable element is introduced at a new site, and the old copy always remains at the original site during replicative transposition. Transposable elements are thought to have played an important role in the evolution of many organisms. All of the above statements correctly describe a DNA transposon....

Which of the following is NOT a feature of RNA processing in eukaryotes? a. Caps and tails are added to RNA transcripts before they leave the nucleus b. Multiple genes are represented in one mRNA from an operon c. Introns are removed and exons are spliced back together to make mature mRNA d . "Alternative splicing" means that one gene in the genome can encode multiple products e. The sequence that codes for one eukaryotic gene is not a continuous...
