1. Organic samples are collected from the crime scene. Care must be observed in such collection.
2. In the laboratory, DNA is extracted from the samples. Specific scientific processes are employed.
3. The extracted DNA is cut into fragments. An electronic process is employed.
4. The DNA fragments are separated into bands. The bands are set in a gel.
5. The DNA band pattern is transferred to a nylon membrane. The transfer is from the gel substance.
6. At this point, a radioactive DNA probe is prepared. The probe will be used in conjunction with the DNA sample.
7. The DNA probe is brought into contact with the DNA sample. The DNA probe binds to specific DNA sequences present on the membrane.
8. The excess DNA probe is washed away. Only that which matched the DNA sample remains.
9. The DNA probe is bound to the DNA pattern on the membrane. The DNA pattern from the sample is now fixed.
