DNA Amplification is the first step in the DNA analysis process.

It is recommended to touch your face, mouth, or body when handling DNA evidence.

All DNA samples should be frozen immediately after collection to prevent degradation.

A reference sample from the victim's muscle tissue is an example of DNA evidence collected from a crime scene.

Sterile gloves are not necessary for DNA evidence collection.

The goal of the DNA analysis process is to obtain a full DNA profile from an unidentified DNA sample.

Coughing or sneezing over evidence can potentially contaminate the DNA sample.

Bloodstains from a crime scene are not suitable for DNA analysis.

The results of a forensic DNA test are not searched in a DNA database.

The scraping method is used to collect DNA evidence from body fluid stains, such as blood or saliva.

Biohazard labels are not necessary for packaging DNA evidence.

When collecting fingernail clippings, it is recommended to use the same clipper/scissor for both hands.

Cigarette butts should be collected and packaged together in a single envelope.

It is recommended to handle evidence with bare fingers to prevent DNA degradation.

When collecting hair evidence, it is recommended to use a single pair of forceps for all samples.

Swabbing a wet stain should be done with a dry swab.
