Slipped Strand Mispairing

Slipped strand mispairing (SSM) 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. Slipped strand mispairing has also been shown to function as a phase variation mechanism in certain bacteria.

Famous quotes containing the words slipped and/or strand:

    Oh! I have slipped the surly bonds of earth,
    And danced the skies on laughter-silvered wings ...
    And while with silent lifting mind I’ve trod
    The high, untrespassed sanctity of space,
    Put out my hand and touched the face of God.
    John Gillespie Magee (c. 1922–1941)

    Dust rises from the main road and old Délira is stooping in front of her hut. She doesn’t look up, she softly shakes her head, her headkerchief all askew, letting out a strand of grey hair powdered, it appears, with the same dust pouring through her fingers like a rosary of misery. She repeats, “we will all die”, and she calls on the good Lord.
    Jacques Roumain (1907–1945)
