a: DNA fingerprinting ~
b: a personalized bar code
What:
"My technical specialty is DNA fingerprinting, a laboratory procedure that helps us correctly identify and track the DNA samples we process. The results look like a bar code that retail stores use to scan purchases. It serves a similar purpose too. The DNA sequence of any individual is unique. So a DNA fingerprint is like a personalized bar code"
