Finding genes and detecting mutations
... insertions/deletions of < 10bp are harder to detect. Small changes such as single base mutations can be detected in many ways • Purify DNA fragment to be analysed, usually by PCR. A label (radioactive or fluorescent) can be incorporated at this stage. – You can also start with mRNA, by first reverse ...
