Yes, pubic hair does contain DNA. Hair itself is composed of keratin, which does not contain DNA, but the root and follicle attached to the hair, if present, contain genetic material. Forensic experts often use these roots to extract DNA for identification purposes. Therefore, care should be taken when handling hair evidence to avoid contamination and preserve the material for accurate analysis.

FAQs & Answers

  1. Can you get DNA from pubic hair? Yes, DNA can be extracted from the root and follicle of pubic hair, making it valuable in forensic investigations.
  2. What part of the hair contains DNA? The hair root and follicle are the parts of hair that contain DNA, while the hair shaft itself is composed of keratin and does not have genetic material.
  3. How is DNA extracted from hair samples? DNA is extracted from hair samples by isolating the root and follicle, which contain the genetic material needed for analysis.
  4. Why is it important to avoid contamination of hair evidence? Contamination can lead to inaccurate results in DNA testing, so it's crucial to handle hair evidence carefully to preserve its integrity.
