5 Bromo uracil can pair with _____________(a) Uracil(b) Thymine(c) Guanine(d) CytosineThe question was posed to me in an online quiz.This key question is from DNA Mutation in chapter DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics

Answer»

The correct option is (c) Guanine

Explanation: This is a BASE ANALOGUE that is a PYRIMIDINE. Under normal CONDITIONS it behaves LIKE T and base pairs with A; but under abnormal conditions, it behaves as C and Base pair with G. As a pyrimidine can’t base pair with another pyrimidine, G is the only available option.
