Running Head : and Forensic Science[Name][Institution][Instructor][Course] and Forensic ScienceIntroductionSince the advent of criminal investigations , investigators have sought a gold standard for the rating of rhetorical evidence . For nearly a century , fingerprints were considered a unique identifier until recent failures in the technology resulted in increase scrutiny from the scientific community (Stacey , 2005 . has usurped the role of fingerprints as the some powerful means of identification currently available . fleck the foundation of forensic testing technology is firmly grow in science , the lack of an objective computational methodology for the interpretation of testing results allows for the introduction of subjectivityThis explores application in forensic science . First background information on is presented . thus , issues related to testing argon reviewed . Following , importance to forensic science and police agencies is considered . Finally , some conclusive remarks are presentedBackground to runs the blueprint of the homophile body (Campbell , 1996 . Almost all kind cells contain . Most human is wrapped into 23 pairs of chromosomes deep down all(prenominal) cell . Half of each chromosome pair is acquire from the individual s mother and half comes from the individual s father . Chromosomes each contain many functional components called divisors . When it is possible to distinguish betwixt two or more variants of a single gene , those variants are called alleles . At the finest direct of scale , chromosomes and genes can be described as a sequence of nucleotides (named for the nitrogenous bases they contain . Nucleotides are present in four forms : adenine (A , one thousand (G , cytosine (C , and tonne (T . In its typically double stranded form , an A on one strand evermore pairs with the T on another , and a C pass on always pair with a G . This association is called a base pair (Dennis et al 2002 .

At this level , the acquainted(predicate) double helix can be visualized (see dactyl 1Figure 2 .1 : being unraveled from the nucleus of a cell (The field of study Health Museum , 2008The lucre-phosphate backbone creates the familiar double helix and is make up of linkages between the phosphate of one nucleotide and the sugar of the adjoining nucleotide . The interior of the double helix is do up of pairs of nitrogenous bases , held together by hydrogen bonds The brotherhood of bases is specific : adenine (A ) can only pair with thymine (T ) and cytocine (C ) can only pair with guanine (G . is grouped into 23 pairs of separate chromosomes and resides in the nucleus of all nucleated cells (Campbell , 1996The human genome contains approximately 3 .12 billion base pairs and is virtually indistinguishable between all human (Dennis et al , 2002 . A note of hand is often made between meaningful (e .g . genes or the regions containing the cryptograph information for proteins and other gene products ) and non-coding , or junk that holds no known function Even distantly related humans are approximately 99 .5 identical at this level of their (Dennis et al , 2002...If you want to get a full essay, golf club it on our website: Orderessay
