Practice question

Microsatellites consist of short tandemly repeated DNA motifs of one to six base pairs, such as dinucleotide CA repeats, repeated five to fifty times. They are also termed simple sequence repeats because of this simple, repetitive organization. Their high mutation rate through DNA polymerase slippage during replication creates extensive length polymorphism. VNTR includes minisatellites with longer repeat units of ten to sixty base pairs, SNP denotes single base changes, and indels represent insertion-deletion polymorphisms, all structurally different from microsatellite architecture.
