DNA analysis is the process of examining and interpreting an individual's genetic material to gain insights into their genetic makeup, ancestry, and predisposition to certain diseases or traits. This type of analysis is commonly used in forensic investigations, paternity testing, medical diagnostics, and ancestry tracing. It involves various techniques such as DNA sequencing, polymerase chain reaction (PCR), and gel electrophoresis to analyze and compare DNA samples. DNA analysis has revolutionized the fields of genetics, biology, and medicine, providing valuable information for a wide range of applications including personalized medicine, genetic counseling, and criminal investigations.
