Fields of Forensic Science
What is the name of the science field that studies bones?
Anthropology
What is the name of the science that uses techniques or tests in connection with the detection of crime.
Forensic Science
What does DNA stand for?
Deoxyribonucleic acid
Based on a narrow pelvis and protruding forehead of the skull what gender is the victim?
The victim is male.
What field of Forensic Science evaluates crime scene evidence in relation to time of death?
Pathology
A person who carries out a harmful, illegal or immoral act.
Perpetrator/Criminal
What are the base pairs of DNA?
Guanine and Cytosine
Thymine and Adenine
Who is the victim? There was a humerus measuring 34cm and appeared to be male.
Formula: 2.89x length of humerus +70.64
Is it Ben (height =174.68), Juan (height =180.46) or Shaun (height =168.90)
Shaun is the victim
What is the study of insects and their relationship to humans, the environment and other organisms?
Entomology
What is the standards of behaviour; principles of right and wrong
Ethics
Name 3 benefits of DNA databases
Any of the following:
Provide an additional layer of evidence
Increase the accuracy of arrests and convictions to reduce crime.
Deter crime and reoffending.
Take serial offenders off the street more quickly as it makes it easier for law enforcement to identify offenders.
Minimise crime rate because offenders will be scared to re-offend since they can be caught quicker.
Cost-effective
Can facilitate information sharing between countries.
There was a recent homicide and you need to determine if the bones you have found are your victim Mary(height = 148.48) or Suz (height =153.98). The female humerus measured 28cm
Use the following formula:
(2.75 x length of humerus) + 71.48
Mary
What field of science studies the DNA testing, fingerprinting and trace evidence?
Biology
What is the activity of collecting information about someone, especially a criminal, in order to give a description of them
Profiling
Name 3 disadvantages of DNA databases.
Any of the following:
Risks of information being hacked and used unethically to discriminate such as to refuse someone a visa or a job.
Inaccuracy of the data stored- DNA collection is susceptible to human error and can not be 100% accurate.
Positive errors from the forensic laboratories will have the potential to destroy lives and reputations due poor laboratory practices can lead to cross-contamination or mislabelling of samples, and test results can be mis-interpreted.
There are two different bones found at a crime scene. One is a female femur measuring 42cm and a male humerus measuring 39cm.
Using the formulas below what height is one of the victims. (1.95 x length of female femur)+72.85
(2.89 x length of male humerus) + 70.64
Female victim is 154.75cm
Male victim is 183.35cm
