How does DNA forensics relate to biology?
DNA forensics uses biological techniques to analyze DNA samples collected from crime scenes or individuals for identification purposes. It relies on principles of molecular genetics and biology to match DNA profiles to known individuals or link DNA evidence to specific crimes. Understanding biological concepts like DNA structure, inheritance, and variation is essential for interpreting forensic DNA evidence accurately.
In what courtroom role may forensic accountants be thrust as expert consultants?
expert consultants may be engaged to assist attorneys by identifying and recommending expert witnesses, helping attorneys to prepare for testimony, and reviewing various documents.
How do forensic scientists use hair and teeth?

What is the goal of computer forensics?
Computer forensics is a branch of digital forensic science which serves as a source of legal evidence found on computers and digital storage media. It aids the investigation of both criminal and civil proceedings by helping obtain vital information and gathering proofs and evidence.
Why is objectivity important in forensic science?
The answer lies in the definition of the word itself.
Objective : not influenced by personal feelings, interpretations, or prejudice; based on facts; unbiased: an objective opinion.
in otherwords so that any reasonable person setting aside their own interpretations, feelings and prejudice would come to the same conclusions. In order that the facts of the matter can be said to be definitive.
Where do you take the glass with the finger print?

How many fingerprint points you need to make a match?
The points are called "Minutiae". For a DA, ADA, or any prosecuting attorney to make a case off your finger prints they will need at least 10 Minutiae Points. Of course the more the merrier. The more would make the case stronger. But 10 will do it.
Is blood typing reliable and accurate in forensic science?
Yes, blood type is reliable and accurate. When forensic scientists collect blood from the crime scene and/or the victim (blood is an example of "physical evidence"), they use the blood to match it up with whoever was at the crime scene. It could belong to either the victim--who might have died a violent death--or it could belong to a suspect.
Why is science important for a forensic scientist?
Forensic scientists need to know about DNA, how to calculate density, and other science things to be able to perform their jobs well. If they don't know ANY science, it wouldn't help solving a crime because they would, for example, need to match DNA to another person's.
What forensic odontology is the study of?
Teeth. When a body is left in an unidentifiable state, the odontologists identify the person by looking at his/her dental records, his/her teeth, etc.
The terms are when a investigator go to the crime scene make sure to check for clues

So You Can Smoke More Weed And Find All The Seed Before Your RWT(Roll Weed Time)
Are some forensic tests not conclusive?
Yes, almost any measurement has a range of uncertainty. In addition, you must consider the errors inherent in taking samples, and the expert opinion on the reliability of the test method.
With fingerprints for example, these are commonly considered infallible. But that depends upon how many points of comparison were made. [The points of comparison are forks, whorls, arches, and so on of the fingerprint ridges.] Currently, a 7 point match is considered good, but a 4 or 5 point match is much more suspect.
In science in general, peer review of test methods is one of the 'gold standards'. In the case of fingerprints, say, the peer review test should be carried out on a number of prints, at a number of laboratories.
Seldom does evidence presented have such a quality history.
