DNA analysis is a scientific method used to examine the genetic material found in living organisms. It plays a crucial role in various fields, including forensics, medicine, and ancestry research. By analyzing DNA, scientists can identify genetic disorders, trace lineage, and even solve criminal cases. The process typically involves extracting DNA from a sample, amplifying it using techniques like PCR (Polymerase Chain Reaction), and then sequencing it to read the genetic code. This information can provide insights into an individual's health, ancestry, and biological relationships, making DNA analysis a powerful tool in modern science.
