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. Witryna18 maj 2024 · Moreover, imperfect repeats were more colligated to genomic abundance of TEs than perfect ones except in Garb; where perfect repeats were more related than mismatched ones. This relatedness was further affirmed by Pearson correlations and significance determined at 0.05 (Table 3).

A critical component of the SSM model for repeat formation is the occurrence of chance mutations that produce a few tandem repeats facilitating the first strand slippage event. bird deterrent window cling decals
