Homework Answer on Forensic Biology
Forensic biology can be applied when there is DNA evidence at the crime scene. This is since the profile of the person can be found within the database and therefore the suspect will be identified and if the profile is not in the crime database the DNA profile remain in the system until the hit is identified.eg. When the suspect wants to register for national ID or passport their information and DNA will be taken as result of the finger prints taken.
It can also occur when the suspect is taken to hospital. Another occasion where forensic biology may be used is when determining the time of a victims death (Police Link, 2016). This done using forensic entomology which is a form of forensic biology where a study of the growth of the growth of insects is drawn from the decomposing body. DNA can also be used be used when there is need to clear or exonerate a person wrongfully accused or convicted.
Example of where forensic biology should be used is when a man is accused of rape. The man may be ordered to provide a DNA sample and this information is referenced with the DNA sample obtained from the victim’s sexual organs to identify whether there is any match. Another example is when the investigation needs to determine the date of death of a victim. In this case the analysis of the growth stage of decomposing micro organism in the victim is used to determine the date of the death or the approximate time of death (Jonquiere’s, Perrin, Durand, Arnold & Lochon, 1998).
