The figure shows the restriction enzyme cutting sites `(R1-R3)` in wild type (n) and mutant (n) gene. img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/NCERT_FING_BIO_OBJ_XII_BPP_C11_E01_102_Q01.png" width="80%" 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 yout expect ?  Note : L1 : wild type DNA, L2: mutant DNA
