1. In our presentations, we see several common techniques used in molecular genetics. These include CRISPR/Cas9, generation of iPSCs, DNA Sanger sequencing, FISH, immunohistostaining, DNA methylation assay, PCR, quantitative RT-PCR, western blot. From this list, pick two techniques that identify mutations at the DNA level. For each technique, explain what kind of changes can be detected and how it works.
