Demonstrate the storage procedures for DNA testing evidence.
DefinitionDemonstration should include
- separating and excluding any other biological evidence from DNA test evidence
- preserving DNA material
- following standard operating procedures for forensic laboratories.
- What are the typical standard operating procedures for DNA evidence in forensic laboratories?
- What steps are involved in storing and protecting DNA test evidence?
- What would happen if DNA preservation methods were not followed?
