DNA Profiling vs. DNA Sequencing: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on January 22, 2024
DNA profiling is identifying unique genetic patterns, while DNA sequencing is determining the exact order of nucleotides in DNA.

Key Differences

DNA profiling, also known as genetic fingerprinting, involves identifying specific patterns in an individual's DNA for identification purposes. It is widely used in forensic science. Conversely, DNA sequencing is the process of determining the precise sequence of nucleotides (adenine, thymine, cytosine, and guanine) within a DNA molecule.

The technique of DNA profiling is often used in criminal investigations and paternity testing, focusing on analyzing specific areas of the DNA where variations are common among individuals. DNA sequencing, on the other hand, involves reading the entire genetic code or specific genes to understand genetic information, which is crucial in fields like genomics and molecular biology.

DNA profiling does not provide information about the genetic traits or health of an individual. It is primarily used for matching DNA samples. In contrast, DNA sequencing can reveal detailed genetic information, including mutations that may lead to diseases, and is essential in medical research and diagnostics.

DNA profiling examines a relatively small set of DNA regions, while DNA sequencing examines the entire sequence or large sections of DNA. This comprehensive approach of DNA sequencing allows for in-depth study of genetic variations and evolutionary relationships.
