The use of DNA sequencing has also led to the development of new forensic techniques, such as DNA phenotyping, which allows investigators to predict an individual's physical characteristics based on their genetic data. In addition to its applications in forensic science, DNA sequencing has also been used in medical research and diagnosis.
Only a few years after James Watson and Francis Crick deduced the structure of DNA, and nearly two decades before Frederick Sanger published the first method for rapid DNA sequencing, Richard Feynman, an American physicist, envisioned the electron microscope as the tool that would one day allow biologists to "see the order of bases in the DNA chain".

Genetic genealogy is the use of genealogical DNA tests, i.e., DNA profiling and DNA testing, in combination with traditional genealogical methods, to infer genetic relationships between individuals. This application of genetics came to be used by family historians in the 21st century, as DNA tests became affordable.
“DNA testing can open up this Pandora’s Box that nobody in the DNA industry talks about,” he said. Burke said some people just want to know about genetic health conditions they may carry.
Personal genomics or consumer genetics is the branch of genomics concerned with the sequencing, analysis and interpretation of the genome of an individual. The genotyping stage employs different techniques, including single-nucleotide polymorphism (SNP) analysis chips (typically 0.02% of the genome), or partial or full genome sequencing.
Millions of people use genetic testing companies like 23andMe to learn more about their ancestry and health. But a new data breach is highlighting the risks of having your ancestry information ...
Her death was ruled a homicide. Detectives collected DNA samples from her body that presumably belonged to the killer, interviewed people of interest and administered polygraph tests. No suspect ...
DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.
