- A The complete genome-wide DNA sequence read out in full by Sanger sequencing
- B Unique Variable Number Tandem Repeats (VNTR/STR) patterns
- C Blood type determined by surface antigens present on red blood cells
- D Protein analysis of serum samples separated by isoelectric focusing
Correct answer: B. Unique Variable Number Tandem Repeats (VNTR/STR) patterns
Explanation: DNA fingerprinting: each person has unique patterns of short tandem repeats (STR/VNTR). These are visualized by gel electrophoresis.
