Why is a biometric security system that relies on DNA authentication vulnerable?

If you can obtain a piece of the person - you've got their DNA so it is possible by sleight of hand to impersonate someone else. Some other drawbacks:
DNA matching is not done in real-time
Intrusive: a physical sample must be taken, while other biometric systems only use an image or a recording
Civil liberty issues and public perception
Also, DNA is extremely complex stuff so biometric security systems that rely on it have a known risk of false negatives.

Different between authentication and access control?
Authentication is the process of verifying the identity of a user, typically through credentials like usernames and passwords. Access control, on the other hand, is the practice of restricting and controlling user access to resources based on policies or rules, regardless of their identity.
