DNA finger printing refer to:
Correct answer: B. Molecular analysis of DNA profiles to identify individuals
- A. Techniques used to identify physical fingerprints of individuals
- B. Molecular analysis of DNA profiles to identify individuals
- C. Use of imprinting devices to analyze DNA samples
- D. Combination of physical fingerprint identification and DNA analysis using imprinting devices
Explanation
DNA fingerprinting, also known as DNA profiling, is a molecular technique used to identify individuals based on unique patterns within their DNA. This method analyzes specific regions of the DNA, such as short tandem repeats (STRs), which vary greatly among individuals but are inherited. This variation allows for the creation of a unique genetic profile for each person. It is widely used in forensic science for solving crimes, as well as in paternity testing and genetic research.Option A is incorrect because it relates to physical fingerprint analysis, not DNA. Option C is incorrect because imprinting devices are not used in DNA fingerprinting. Option D is incorrect because it inaccurately combines unrelated processes, whereas DNA fingerprinting focuses solely on molecular DNA analysis.
