Inverted duplicates are a type of repetitive DNA motifs consist of two copies of reverse
complementary sequences separated by a spacer sequence. They can lead to genome
instability and many may have no function, but some functional small RNAs are processed
from hairpins transcribed from these elements. It is not clear whether the pervasive numbers
of such elements in genomes, especially those of mammals, is the result of high generation
rates of neutral or slightly deleterious duplication events or positive selection for …
