If you commit a crime, you need to make sure that you do not leave even the smallest speck of blood, hair, or other organic matter from your body. If you do, the DNA in this material can be amplified by ________, subjected to genetic analysis, and used to identify you as the perpetrator of the crime.
A)PCR
B)STR analysis
C)RFLP
D)restriction digests

Question

Quizplus · Accepted Answer

PCR (Polymerase Chain Reaction) is a method used to amplify DNA in small samples, making it possible to analyze and compare DNA from a crime scene with that of a suspect. It is a highly sensitive and specific technique that can detect even the smallest amounts of DNA, making it an effective method for forensic analysis. PCR can be used in conjunction with STR analysis (Short Tandem Repeat analysis) or other genetic techniques to produce a DNA profile that can be matched to a suspect. RFLP (Restriction Fragment Length Polymorphism) and restriction digests are older techniques that have been largely replaced by PCR-based methods due to their lower sensitivity and higher cost.
