DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics.DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding.
Modern day technology has evolved beyond RFLP. Short Tandem Repeat (STR) analysis is the modern day equivalent of RFLP. Not only does STR analysis use less of a sample to analyze DNA, but it also is a part of a larger process called Polymerase Chain Reaction (PCR). PCR is a process that can be used to quickly reproduce up to a billion copies of ...
Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer. Genetic analyses of cancer include detection of mutations, fusion genes, and DNA copy number changes. FDA microbiologist prepares DNA samples for gel electrophoresis analysis
Lab tested DNA for Kristin Smart case in 2021. In 2022, SERI senior forensic DNA analyst Angela Butler testified during the Smart trial that the lab tested for both the presence of human blood and ...

STR analysis is a tool in forensic analysis that evaluates specific STR regions found on nuclear DNA. The variable (polymorphic) nature of the STR regions that are analyzed for forensic testing intensifies the discrimination between one DNA profile and another. [3] Scientific tools such as FBI approved STRmix incorporate this research technique.
A Colorado Bureau of Investigation DNA analyst intentionally manipulated data in the testing process for at least 15 years, according to an internal affairs investigation.
Genetic testing, also known as DNA testing, is used to identify changes in DNA sequence or chromosome structure. Genetic testing can also include measuring the results of genetic changes, such as RNA analysis as an output of gene expression , or through biochemical analysis to measure specific protein output.
