Is DNA evidence reliable?

DNA evidence is generally very reliable because it’s unique to each individual, like a biological fingerprint. However, its accuracy depends on proper collection, handling, and analysis. Mistakes such as contamination, mislabeling, or partial samples can lead to errors. Advances in technology have improved reliability, but results should be considered along with other evidence. In summary, DNA is a powerful tool in investigations, but like any method, it’s most effective when used carefully and contextually.
