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 duplicated

I 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

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.
