Questions and Answers

What is the CSI effect?

The CSI effect refers to the influence of crime shows on the public's perception of forensic science, often leading to unrealistic expectations of the capabilities of forensic evidence.

Why do average people sometimes have unrealistic expectations of forensic science?

Average people may have unrealistic expectations of forensic science due to the portrayal of forensic techniques in television shows, which often exaggerate the accuracy and speed of forensic analysis.

What can fingerprints reveal about a person?

Fingerprints can provide information about the individual's biological matrix, including molecules present in sweat, which can be used to gather information about the person.

What technology is being used to analyze sweat profiles?

<p>MOLVE technology</p> Signup and view all the answers

How does the MOLVE technology work?

<p>A UV laser is used to fire on the surface of the item where the molecules are sitting. The molecules come out of that surface and absorb. These molecules are charged and called ions. By measuring the weight of the ion, the identity of the molecule can be determined.</p> Signup and view all the answers

How has this technology advanced forensic research?

<p>This technology can detect specific molecules present in a fingerprint, such as a polymer from a condom lubricant. This can provide molecular information and link the individual to the crime.</p> Signup and view all the answers

What is familial searching and how does it differ from the CODIS database?

<p>Familial searching is a type of DNA testing that utilizes the CODIS database to identify potential relatives of an individual. It differs from the CODIS database in that it does not look for exact matches, but rather tries to identify individuals who may be related to the DNA sample.</p> Signup and view all the answers

How do at-home genetic testing companies like Ancestry.com and 23andMe differ from the CODIS database in terms of the information they provide?

<p>At-home genetic testing companies focus on providing information about an individual's heritage and traits, while the CODIS database is used for identifying individuals through exact DNA matches.</p> Signup and view all the answers

What is next generation DNA testing and how can it provide additional information?

<p>Next generation DNA testing is a new method that can provide a portrait or image of what an individual might look like based on their DNA. This technology can provide additional information beyond just identifying an individual.</p> Signup and view all the answers
