Forensic Science And Forensic Science

Forensic science, known as forensics, is the application of science to law by analyzing DNA for legal evidence. DNA profiling is the predominant application and forensic science, DNA profiling allows us to take more than one sample of an unknown DNA specimen and determine if it has the same genetic match. Moreover, DNA profiling is to help determine and solve crime scenes such as murders, assaults, and rapes. The technique used for analyzing DNA is restriction fragment length polymorphism testing. It restricts the enzyme, which cuts DNA at specific sequence to break into small pieces, distinct based on location within the DNA of some specific sequence. This allows a person’s DNA to be generate and since a person’s DNA contains small differences in one of the restriction sites resulting in a different profile of restricting active fragment. Secondly, PCR is another technique wears scientist can obtain, targeted, and quickly and precisely analyze DNA in a short amount of time through blood or tissue samples to allow DNA profiling. In PCR, the samples mixed with nucleotides, replication enzymes, and other ingredients. This solution exposed to heating and cooling cycle. During the heating and cooling d specific regions of the DNA molecules to replicate. After all this is completed then this allows the …show more content…
Population is a group of the same species living in the same environment. Evolutionary adaptation is where a population increases in traits to adapt to their environment. For instance, lizards adapts to their environment by camouflaging themselves when it gets too hot, cold, or to hide themselves from predators to survive. One of the first evidence of evolution discovered was a fossil of prokaryote cell. Which proved, that all life’s ancestral species began over 3.5 million years ago. (Simon, Dickey, & Reece,
