WebSlipped 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. http://benchpartner.com/q/does-dna-replication-occur-in-cell-division-one-characteristic-of-the-dna-molecule-is-its-replication-capability-what-are-the-consequences-of-failures-during-dna-replication
