    acid (DNA) collection and its relationship to solving crimes. The collection of DNA is one of the most important steps in identifying a suspect in a crime. DNA evidence can either convict or exonerate an individual of a crime. Furthermore‚ the accuracy of forensic identification of evidence has the possibility of leaving biased effects on a juror (Carrell‚ Krauss‚ Liberman‚ Miethe‚ 2008). This paper examines Carrells et al’s research along with three other research articles to review how DNA is collected

    by Georg Wittig in 1954‚ the Wittig reaction is a robust organic synthesis method for preparing stereospecific alkenes. In general‚ Wittig reactions involve an aldehyde or ketone and a Wittig reagent (triphenylphosphonium ylide) and result in the formation of an alkene product and triphenylphosphine oxide (side product). Stereospecific alkene products can be synthesized by adjusting the reaction reagents and conditions. In the 60 years since the Wittig reaction was discovered‚ many articles have

    DNA profiling is a method of identifying an individual by unique characteristics of their DNA. A specific DNA pattern‚ called a profile‚ is obtained from an individual or a sample of tissue. This allows the comparison of the base sequence of two or more DNA samples to determine whether they are related. DNA profiling has many uses‚ in prevention of economic fraud‚ dietetic work‚ and classifying species‚ identifying bodies‚ forensic science‚ screening for disease‚ and investigating paternity.
