D)RFLP analysis

Question

Quizplus · Accepted Answer

STR analysis (Short Tandem Repeat analysis) is the current standard tool used by forensic scientists for DNA profiling. It is a highly specific and sensitive method that analyzes short, repeated DNA sequences to create a DNA profile that can uniquely identify an individual. It is faster, more accurate and less error-prone than older methods like RFLP analysis (Restriction Fragment Length Polymorphism analysis) and has become the preferred method for forensic DNA typing since the mid-1990s. Gene cloning and genetic engineering are not used for DNA profiling in forensic investigations.
