Solution
The correct option is B Individual ‘B′
Individual "B" may be involved in the crime as his DNA fragment matches the DNA segment from the crime scene. Genes are short sequences present in DNA strand that are responsible for the particular characteristics of an individual. PCR is a technique used to amplify the DNA molecules present in a small sample in order to obtain a large amount of DNA sequence for the test. This is followed by restriction fragment length polymorphism (RFLP). RFLP analysis is used to identify the repeated sequences by detecting a specific sequence pattern of Variable Number Tandem Repeats which becomes that individual's DNA profile. This is the basis of DNA fingerprinting.
