If you have ever heard about the dna profiling gizzmo, you are likely curious about how it works. These genetic tests are incredibly popular and can give you valuable information about your own family history. This test can be used to determine if two people are related. The process can be confusing, especially if the technical terms involved are not understood. Fortunately, there is an answer key to this DNA profiling gizmo.
The DNA Profiling Gizmo allows students to learn about the scientific principles behind DNA fingerprinting, and they will use this tool to solve real-life crimes. One such case involved a learning-disabled teen who confessed to a violent crime. Similar assaults had occurred in the same area two years prior. This technology will allow police and forensic scientists to find the true culprit behind a number of crimes, including murder and sexual assault.
DNA profiling works by comparing the DNA sequences of two people. These two DNA profiles are almost identical. The difference is that each person has two copies of a chromosome. Unlike the chromosomes, the regions between the genes are almost identical. Different disorders can be caused by changing the sequences of these areas, including mental illness and cancer. With DNA profiling, it is possible to identify a person.
