exist to assist law enforcement officials in identifying a criminal suspect. The technological advances that continue to assist the criminal justice system in these identifications are Deoxyribonucleic Acid (DNA) analysis, biometric identification, Intra-agency databases for DNA, fingerprinting and palm printing, and camera and wiretap surveillance. Each aspect serves a specific purpose in making certain that the right person is properly identified for the crimes that they commit. Each technological

on T.V. is 100% true. Actually what you see on T.V. is mainly false or over exaggerated in some way. Criminal Investigation is the largest and most known form of Forensic Science. More of the known areas that people know about Forensics are; Fingerprinting, DNA Identification, Fiber Samples, Computer Animation, etc. What people see on T.V. is that it takes about an hour for the people on the NCIS, or Law & Order to figure everything. Typically it takes months at a time, and most of the time aren’t

2012 Fingerprinting DNA fingerprinting, also called DNA profiling, applies a test to determine the unique DNA sequence that each person has for the purpose of identification. In the 1930s, police detectives found each person has different patterns on the tips of the fingers, and these fingerprints became the standard for identification. However, the finger patterns can be altered by surgery or other means. DNA within living cells is difficult to alter

Chromatography which literally means “color writing” was invented by Mikhail Tsvet, a Russian botanist in 1903 while studying the coloring materials in plant life. It is defined as a laboratory technique utilized by scientists for the separation of organic and inorganic mixtures into their respective components in order to analyze, identify, purify and/or quantify the mixture or components. There are different types of chromatography which are use including liquid chromatography, gas chromatography

The term “proteome” or “proteomics” was first introduced in 1995. Proteomics is the characterization and identification of all proteins that expressed by a genome or tissue and understanding how these proteins function (Mohanty, 2005). Besides, the purpose of proteomics is not only to recognize all the proteins in a cell but also to generate a complete three-dimensional (3D) map of the cell indicating where the proteins are located. To achieve these goals require the involvement of a large number

simple idea—the instructions for making all this life are written in nucleic acids, usually DNA. Most organisms have a set of DNA that contains the instructions for making that creature. This DNA contains four “letters” in which these instructions are written—A, T, G, and C. The only difference between the code for a dog and the code for a geranium is in the order of those letters in the code. If you took the DNA from a human and rearranged the letters in the right way, you could produce an oak tree—arrange

1. Write an essay on protein structure and synthesis Protein synthesis is a cellular process leading to the production of proteins. This term is also synonymous to protein translation. It begins with a sequential process of transcription of DNA into mRNA, which is then used as input for translation after exon-intron splicing. The addition of successive tRNA molecules based on the code of mRNA matched up by base-pairing through their anti-codons in the ribosomes creates the nascent protein. After
