Question

A gene acquires a point mutation that eliminates its stop codon. RNA is extracted from a wild type strain and one with this mutation, and a northern blot is performed with a probe specific for this gene. What result are we going to see? Select the best answer.

A . The wild type and mutant bands will be identical

B. The mutant band will be found higher on the gel than the wild type band

C. The mutant band will be found lower on the gel than the wild type band

D. The mutant band will be found at the same spot of the gel but will be more intense

Explanation / Answer

B. The mutant band will be found higher on the gel than the wild type band.

The mutant band will have a higher molecular weight than wild type band.
