The figure shows the restriction enzyme cutting sites (R1-R3) in wild type (n) and mutant ( $n^{-}$ ) gene.
If a radioactively labelled probe (that hybridises at a sequence close to R1) is used for detecting the presence of DNA fragments after gel electrophoresis and Southern blotting, which of the following band patterns will your expect?Note: L1 : wild type DNA, L2 : mutant DNA
