Q. Consider the following statements regarding DNA Barcoding:
1.It uses a short, standardized DNA sequence (usually 400-800 base pairs) to identify a species.
2.It allows for the identification of an unidentified sample by comparing it against a digital library of known barcodes.
3.DNA barcoding is limited to identifying animal species and cannot be used for food safety assessments or detecting invasive alien species.
Which of the statements given above are correct?
Answer: A
Notes:
Explanation:
- Statements 1 and 2 are correct: This is a high-speed identification method.
- Statement 3 is incorrect: DNA barcoding has wide applications, including food safety (checking for mislabeled fish), identifying endangered species, and detecting invasive plants.
