A piece of DNA that is 3 kb in length is found in many locations throughout the genome.How would you decide whether this was a LINE or a DNA transposon?
A) If it has more than 10,000 copies in the genome, it is a LINE; if not, it is a DNA transposon.
B) If it has more than 10,000 copies in the genome, it is a DNA transposon; if not, it is a LINE.
C) If it contains the sequence GCTCGATC, it is a LINE; if not, it is a DNA transposon.
D) If it uses an RNA intermediate, it is a LINE; if not, it is a DNA transposon.
E) If it uses a "copy and paste" mechanism, it is a DNA transposon; if not, it is a LINE.

LINEs (Long Interspersed Nuclear Elements) are a type of retrotransposon that replicate through an RNA intermediate. This distinguishes them from DNA transposons, which do not use an RNA intermediate but move directly as DNA.
