| Front | How are DNA probes used? |
|---|---|
| Back | - to locate specific alleles of genes - short single-strand of DNA - labelled - radioactive/fluorescent - complementary base sequence to target allele - DNA sample being tested is heated - to break H bonds and separate strands - DNA probe binds to complementary base sequence by DNA hybridisation - viweing fluoresence or autoradiography is used to identify allele of gene |
