The system of DNA profiling used today is based on PCR and uses simple sequences [6] or short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA (the most common is 4 bases repeated, but there are other lengths in use, including 3 and 5 bases).
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 a singular segment of DNA. [3]

A further academic study published in 2009 examined more STR markers and identified a more sharply defined SNP haplogroup, J1e* (now J1c3, also called J-P58*) for the J1 lineage. The research found "that 46.1% of Kohanim carry Y chromosomes belonging to a single paternal lineage (J-P58*) that likely originated in the Near East well before the ...
Synchronous transmit-receive (STR) was an early IBM character-oriented communications protocol which preceded Bisync.STR was point-to-point only, and employed a four-of-eight transmission code, communicating at up to 5100 characters per second over half-duplex or full-duplex communication lines.
A microsatellite is a tract of tandemly repeated (i.e. adjacent) DNA motifs that range in length from one to six or up to ten nucleotides (the exact definition and delineation to the longer minisatellites varies from author to author), [1] [6] and are typically repeated 5–50 times.

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]
