What is Formed When Two IS Elements Insert near Each

Question

What is formed when two IS elements insert near each other?
A) Replicative transposon
B) Composite transposon
C) Inverted terminal repeats
D) Inverted terminal duplications
E) Inverted terminal deletions

Accepted Answer

When two IS elements insert near each other, they can create a composite transposon. This occurs when the DNA between the two IS elements is excised and reinserted elsewhere in the genome.
