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.
The shorter base pair sizes of AmpFLP was designed to work better with the amplification process of PCR. [8] It was hoped that this technique would allow for the discriminating power of RFLP analysis with the ability to process samples that have less template DNA to work with or which were otherwise degraded.
Automated DNA-sequencing instruments (DNA sequencers) can sequence up to 384 DNA samples in a single batch. Batch runs may occur up to 24 times a day. DNA sequencers separate strands by size (or length) using capillary electrophoresis, they detect and record dye fluorescence, and output data as fluorescent peak trace chromatograms.
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology.There are a number of applications that are developed from this research, and these are also considered parts of the process.
The first formal bloodstain training course was given by MacDonell in 1973 in Jackson, Mississippi. MacDonell taught workshops on how to conduct bloodstain analysis, and the newly trained bloodstain analysts, who often had received as little as 40 hours of instruction, in turn would give expert testimony in court cases.

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.
A now-former forensic scientist with the Colorado Bureau of Investigation (CBI) manipulated DNA test results in hundreds of criminal cases, an internal affairs investigation found, which prompted ...
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.
