1.	Which of the following is not a point mutation?(a) Substitution(b) Transposition(c) Insertion(d) TransversionThe question was asked in an interview for job.The doubt is from DNA Mutation in section DNA Mutation, DNA Repair, Transposable Elements of Cytogenetics
Answer» Correct choice is (b) Transposition Explanation: Point MUTATION concerns a single base. Thus SUBSTITUTION, which INCLUDES transversion, and insertion or deletion, FALLS within point mutation. On the other hand, translocation INVOLVES a stretch of bases so it is not a point mutation.
