WitrynaTandem repeats occur in DNA when a pattern of one or more nucleotides is repeated and the repetitions are directly adjacent to each other. ... a tandem repeat search tool for perfect and imperfect repeats - the maximum pattern size depends only on computational power; UGENE - an ultra fast and memory efficient open-source … Tandem repeats can occur through different mechanisms. For example, slipped strand mispairing (SSM), (also known as replication slippage), is a mutation process which occurs during DNA replication. It involves denaturation and displacement of the DNA strands, resulting in mispairing of the complementary bases. Slipped strand mispairing is one explanation for the origin and evolution of repetitive DNA sequences.
