Which of the Following Statements About Mobile Genetic Elements Is

Which of the following statements about mobile genetic elements is TRUE?

A) Mobile genetic elements can sometimes rearrange the DNA sequences of the genome in which they are embedded by accidentally excising neighboring chromosomal regions and reinserting these sequences into different places within the genome.
B) DNA-only transposons do not code for proteins but instead rely on transposases found in cells that are infected by viruses.
C) The two major families of transposable sequences found in the human genome are DNA-only transposons that move by replicative transposition.
D) During replicative transposition, the donor DNA will no longer have the mobile genetic element embedded in its sequence when transposition is complete.
