Final answer:
The procedure known as A)DNA fingerprinting is used to identify individuals by their unique genetic sequences, employing techniques like PCR, use of restriction enzymes, and gel electrophoresis.
Step-by-step explanation:
The procedure used to identify individuals by their unique genetic sequences is known as DNA fingerprinting. DNA fingerprinting, also referred to as genetic fingerprinting, involves a series of techniques including the amplification of DNA by polymerase chain reaction (PCR), the use of restriction enzymes to cut DNA into pieces, and gel electrophoresis to separate these pieces. This creates a pattern that is almost unique to an individual. The amplified DNA is tagged with fluorescent or radioactive isotopes to facilitate the profiling process. DNA fingerprinting is often used in paternity tests, criminal investigations, and forensic sciences to uniquely identify individuals based on their DNA. It helps to match DNA from an unknown sample to a known individual's sequence, to establish a genetic link for investigative purposes.
