An inverted repeat is a nucleotide sequence fragment that can form self-complementary pairing between its two halves. The perfect inverted repeats are also known as palindrome where one of these two halves is exactly the reverse complement of the other; in contrast, imperfect inverted repeats contain nucleotide … Witryna1 lip 2000 · Slipped-strand mispairing (SSM; Levinson and Gutman 1987) is the most often proposed model for repeat formation, expansion, and contraction.

In plants and yeast, the predominant MYBs have two repeats (R2 and R3) (Martin and Paz-Ares, 1997; …

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.
