(December 31, 1969). Sample contamination due to contaminated thermal cyclers has been documented. . In this example, Sample A had bands at the 2-repeat position and the 5-repeat position. PCR-based tests are also extremely sensitive to contaminating DNA at the crime scene and within the test laboratory. . The two strands of this sequence are held together more tightly than a similar length sequence with a 40 G C content for example. . The DNA fragments are shorter in length) than those near the top. . This is idealized and requires the locus be far apart on the chromosome, and also that functional products in the two regions don't interact. .

STR is a generic term that describes any short, repeating DNA sequence. . However, PCR still has sample size and degradation limitations that sometimes may be under-appreciated. .

PCR-based testing often requires less DNA than rflp testing and the DNA may be partially degraded, more so than is the case with rflp. . Full profile contaminants have been documented on multiple occasions and in multiple laboratories. .
