DNA profiling - Wikipedia, the free encyclopedia - 0 views

  •  
    This technique is used to identify the DNA left on a crime scene. Actually, 99.9% of humans have the same DNA sequence, but there is enough unique DNA to identify the person.

Forensic DNA technology: A powerful tool for judicial reform | Science and Technology, ... - 0 views

  • Recent advances in forensic DNA testing are now paving the way for reforming the manner by which cases are resolved in courts of law through the way suspected offenders are apprehended during a criminal investigation. Firstly, the availability of new markers which are more variable across different populations, adds to the increased power of discrimination once more genetic markers are used. From the time when DNA testing only involved seven to nine genetic markers to evaluate if crime scene evidence matches a suspect’s profile, as well as to determine relationships, to the current battery of 21 autosomal markers and 23 male-specific markers, the capacity of DNA profiling to differentiate individuals has increased significantly. The use of automated and expert systems for large-scale analysis has also been found to reduce manual errors and to increase output per unit time. The use of several dyes in a single multiplex system provides more information from the same amount of genetic material compared to reactions targeting only one genetic marker but requiring the same amount of DNA that was common in the early 1990s.

    This is about how they have new technology for forensic DNA sciences, so they make less mistakes and can find the person quickly. For example, they now have automatic systems to test DNA.

    This is just about how in the future, we might have a record of everyone's DNA/ Then, if you find DNA at a crime scene, you can immediately find out who it belongs to.

    DIY kits to find out the possibility of you getting cancer, diabetes, or Alzheimer's. The person who writes the blog is against these kits being sold because they make people wrongly believe they might get that disease.
