Solution
The correct option is B Erythrocytes
The restriction fragment length polymorphism analysis is used to identify the repeated sequences by detecting a specific sequence pattern to the Variable Number Tandem Repeats which becomes that individual's DNA profile. This is the basis of DNA profiling technique. DNA is present in the nucleus and it is present in leucocytes, sperms, and saliva. The nucleus is absent in erythrocytes and so they cannot be used for the detection process. Thus, the correct answer is option B.
