E) plasmids

Question

Quizplus · Accepted Answer

Short tandem repeats (STRs) are the most commonly used markers in the creation of a DNA profile. These are short, repeated sequences of DNA that are highly variable between individuals. They are used because they are reliable, easy to amplify, and have a high degree of variability between individuals, making them ideal for forensic identification. Minisatellites are longer sequences of repeated DNA and are not commonly used. Introns and exons are parts of genes and do not provide much variability between individuals. Plasmids are circular pieces of DNA that are often used in molecular biology research, but are not relevant to DNA profiling.
