If there are two sequences CGCGCGCG and ATATATAT, which will have a higher probability of being duplicated?(a) ATATATATAT(b) CGCGCGCGCG(c) Both will have equal probability(d) Both are unlikely to be duplicatedI got this question in quiz.I would like to ask this question from Chromosomal Abnormalities : Duplication topic in division Chromosomal Basis of Inheritance of Cytogenetics

Answer»

The correct choice is (c) Both will have equal probability

The explanation is: Streisinger model WORKS on REPEATED SEQUENCES, it is not BASE specific. In this case both the AT rich and CG rich sequences should have an equal probability of getting DUPLICATED.
