Forensic Sciences: Biotechnology Strategies And Methods

930 Words4 Pages

Forensic sciences is the term given to an examination and investigation of a crime using scientific means. Forensic science is a fundamental instrument for the recognition or investigation of crime and the ruling of justice, depending on data and information about the evidence found at crime scene. The validity of those results relies on the knowledge, abilities, and experience of the forensic scientist attempting to get them. A forensic researcher must be equipped for incorporating learning and abilities in the examination, investigation, translation, reporting, and testimonial backing of evidence. Forensic examination of biological evidence depending on biotechnology strategies and methods is progressively important in criminal investigations. …show more content…

In old Roman culture, cases including criminal investigation were displayed before a gathering of people in the discussion. Both the victim and suspect would give talk and speeches on their side of the story. The best story or the more convincing argument would decide the result of the case. What are the different areas of forensic science? Forensic science uses many areas of the known science and related them together to create this developed science called forensics. forensic use different part of science such as: 1- Chemistry: Chromatography: which is a method that is used to separate mixture of components between two different phases, and there are many types of chromatography. Spectroscopic analysis: is the investigation of the cooperation between matter and electromagnetic radiation, and this term is used in degraded …show more content…

The main special case to this is identical twins. Scientific researchers in forensic cases can use DNA profiles to recognize criminals. A DNA profile is similar to a genetic unique fingerprint. Get data sheet: DNA profiling The outcomes from DNA profiles may be used as a part of court. like if the samples gathered from a crime scene may give a positive results with the DNA of a suspect. This could be used as proof that the suspect had been available at the crime scene – yet it doesn't say that the suspect carried out the crime and did the wrongdoing thing on the place of the investigation. DNA proof alone is not enough to solve a crime It is most valuable when put close by other confirmation, for example, fingerprints, foot shaped impressions, wrongdoing scene examination and observer accounts. Other biological proofs might be gathered, like blood splash examples (demonstrating the direction of the damage) and microbial data (which may give pieces of information as to the time of death). DNA databanks In New Zealand there is a databank of DNA profiles. It contains more than 70,000 DNA profiles of indicted guilty parties, and a few volunteers. This national databank accumulation can be coordinated against DNA profiles gathered from unsolved

If DNA for Adnan’s case displays that Adnan didn’t have anything to do with the murder, it’s a general rule that that information can be trusted. In addition, according to the National Institute of Justice, “DNA does more than just identify the source of the sample; it can place a known individual at a crime scene, in a home, or in a room where the suspect claimed not to have been.

Looking back at the 1800’s and comparing the technology of the 21st century, the difference is certainly huge. The increase in technology makes information more vast and more ideas can be shared easily. Many sciences are based off many “what ifs” while forensic science is more factual and attempt to solve puzzling occurrences and events and get down to what truly

    DNA has given some innocents their freedom, but others are still being locked up. Jurors are giving guilty verdicts to people who don’t deserve it based on theories and confessions that may have been beaten out of them. It was reported in the studies that exculpatory DNA does sometimes help a defendant that had confessed, but then prosecutors come up with theories and that doesn’t help the defendants, as was the case of Joseph Buffey (Appleby & Kassin, 2016). I didn’t expect for exculpatory DNA not to be taken into consideration when prosecutors told a theory that can explain why DNA of the accused was not at the scene of the crime. It just doesn’t make sense.

    Although, in our lab report, suspect ones DNA matched the crime scene when cut with enzyme one, this can be explained by how closely related the two suspects are. Therefore two enzymes were used to cut the DNA; the suspect has to match both. Moreover, the limitation to DNA fingerprinting is, if a person were to have an identical twin. This is because identical twins have the same DNA because they come from the same egg. If a suspect’s DNA matched that of the one being tested, and they had an identical twin, a farther investigation would need to be done.

    In many cases, post-conviction DNA testing has revealed that the DNA found at the crime scene did not match the DNA of the individual who was convicted. We use DNA to link crimes, DNA evidence can link crimes that were previously thought to be unrelated by identifying the same perpetrator through matching DNA profiles found at multiple crime scenes. Like we identify suspects we can also Identify victims, DNA evidence can be used to identify victims of crimes, such as in cases where the victim's body has been severely damaged or decomposed. Providing evidence in court DNA evidence is admissible as evidence in court and can be presented to a jury to help establish the guilt or innocence of a defendant. DNA evidence has become an important tool in the criminal justice system and has helped to solve many crimes, as well as prevent the conviction of innocent individuals and try so hard to find out who the offenders

These samples can come from many other forms of identification other than fingerprints and bloodstains. A few moderate examples include strands of hair, tiny beads of sweat, and a saliva specimen (“Forensic Science” 12).

A biological profile is a series of characteristics that an individual possessed during life but which critically can also be determined from skeletonized remains after death. To find a biological profile they’ll need to find the age, sex, gender, geographic ancestry, and trauma. They use fragments of bones from skulls and long bones to not only find the sex, age, and gender but sometimes they can find how they died. They also use those bones to find lots of information about that individual.

Several types of biological evidence such as blood and hair are commonly used in forensic science, which is the scientific study of evidence for crime scene investigations and other legal matters. Forensic science is used for the purpose of DNA analysis, this is the analysis of DNA samples to determine if it came from a particular individual. DNA analysis is done by obtaining DNA samples from an individual; next, a large sample of DNA is produced from amplified selected sequences from the DNA collected.
