[1] In other words, the direct repeats are nucleotide sequences present in multiple copies in the genome.
[1] There is no inversion[clarification needed] and no reverse complement associated with a direct repeat.
[1] There are several types of repeated sequences: A tract of repetitive DNA in which a motif of a few base pairs is tandemly repeated numerous times (e.g. 5 to 50 times) is referred to as microsatellite DNA.
Thus direct repeat tandem sequences are a form of microsattelite DNA.
The process of DNA mismatch repair plays a prominent role in the formation of direct trinucleotide repeat expansions.
