Tandem duplication creates ____________and reverse tandem creates_____

1.	Tandem duplication creates ____________and reverse tandem creates_____________(a) Buckling, looping(b) Hairpin, buckling(c) Buckling, Hairpin(d) Loop with turn, hairpinI had been asked this question in my homework.Asked question is from Chromosomal Abnormalities : Duplication in portion Chromosomal Basis of Inheritance of Cytogenetics
Answer» RIGHT choice is (c) Buckling, HAIRPIN Explanation: In case of tandem REPEAT the same sequence in same order is repeated. As parent chromosome has only ONE copy of that sequence the daughter bulges out. This, causes buckling. In reverse tandem the duplication is INVERTED in sequence which leads to formation of hairpin.
