PCR is very specific, the targeted DNA sequence can be _ of total DNA sample.
Correct answer: B. Less than one part in a million
- A. One part in a million
- B. Less than one part in a million
- C. More than one part in a million
- D. Two parts in a million
Explanation
PCR (Polymerase Chain Reaction) is highly specific and can amplify a targeted DNA sequence even if it is present at less than one part in a million of the total DNA sample.
