DNA extraction from super old bones is a tricky process, but it’s possible! Scientists first have to find an ancient bone that is well-preserved. Then, they have to clean the bone to get rid of any dirt or bacteria that might be on it. After that, they use a special solution to dissolve the bone into small pieces. They filter out the pieces and collect the DNA. Finally, they use a technique called PCR (polymerase chain reaction) to make the DNA strands visible so they can analyze it.
