Modern forensic biotechnology labs use sophisticated machines to analyze ________, such as D16, and to determine the number of specific genetic repeats in the samples.

Question

Quizplus · Accepted Answer

Sophisticated machines in modern forensic biotechnology labs are used to analyze STRs, or short tandem repeats, which are specific genetic loci that contain repeated sequences of nucleotides. By determining the number of repeats at certain STRs, investigators can establish DNA profiles and compare them to potential suspects. RFLPs, or restriction fragment length polymorphisms, were previously used in DNA profiling but have since been largely replaced by STRs due to their higher level of discrimination and lower amount of required sample material. Primers and PCRs are both tools used in the process of DNA amplification for analysis, but they do not directly analyze genetic repeats as with STRs.
