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]

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.
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]
The result in the truncated DNA is the same. Some reagents, e.g. DMS, sometimes do not block the reverse transcriptase, but trigger a mistake at the site in the DNA copy instead. These can be detected when using high-throughput sequencing methods, and is sometimes employed for improved results of probing as mutational profiling (MaP). [14] [15]

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 ...
