During Strisinger’s model, what happens?(a) The Ribosome slips which causes duplication(b) Parent strand slippage polymerase(c) Daughter strand slippage polymerase(d) The polymerase back tracks and resynthesizesI had been asked this question during an interview.This is a very interesting question from Chromosomal Abnormalities : Duplication in division Chromosomal Basis of Inheritance of Cytogenetics

Answer»

Right answer is (C) DAUGHTER strand slippage polymerase

The best explanation: Daughter strand slippage will CAUSE looping which is stabilized by repetitive SEQUENCES. This leads to an increase in a number of repeats in the daughter.
