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]
Rapid DNA (UK:Rapid DNA profiling) describes the fully automated (hands free) process of developing a CODIS Core STR profile or other STR profile from a reference sample buccal swab. The “swab in – profile out” process consists of automated extraction, amplification , separation, detection and allele calling without human intervention. [ 1 ]
STR polymorphisms are genetic markers that may be used to identify a DNA sequence. The FBI analyses 13 specific STR loci for their database. These may be used in many areas of genetics in addition to their forensic uses. One can think of a STR multiplex system as a collection of specific STRs which are positionally conserved on a target genome.
(b) Replication of the STR locus has led to a gain of one unit owing to a loop in the new strand; the aberrant loop is stabilized by flanking units complementary to the opposite strand. (c) Replication of the STR locus has led to a loss of one unit owing to a loop in the template strand. (Forster et al. 2015)
Workflow of the differential lysis of a sample of sexual assault evidence is shown. All steps of the stepwise DNA-extraction process are described in detail. First of all human proteins, e.g. human semenogelin antigen, can be optional isolated and immunologically analyzed to quick-check for the presence of human seminal fluid.

This template is used on approximately 179,000 pages. To avoid major disruption and server load, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage.
Experimental approaches of determining the structure of nucleic acids, such as RNA and DNA, can be largely classified into biophysical and biochemical methods. Biophysical methods use the fundamental physical properties of molecules for structure determination, including X-ray crystallography, NMR and cryo-EM.
