DNA analysis is now a common tool of criminal justice and is used in forensics to help identify suspects and in some cases to clear others. This paper will provide the history of DNA analysis, how it is used today, and what the future holds in store for this area as a tool for the field of criminal justice.
DNA (Deoxyribonucleic acid) is a long molecule that carries specific genetic information. DNA is found in the nucleus of every cell in the human body with the exception of red blood cells. Given that DNA is polymorphic, scientists are able to distinguish the DNA of one individual from another, making identification a fairly certain outcome.
Both in civil and criminal cases DNA analysis has become as an important tool to solve cases. In crime scene, evidences like hair, skin, body remains in burnt cases, semen in rape cases etc. will be analysed for DNA matches. In cases such as paternity confirmation also, DNA analysis is being used. This filed of science is Forensic DNA analysis.
Forensic DNA analysis has played a crucial role in the investigation and resolution of thousands of violent crimes since the late 1980s. Currently, short tandem repeats (STRs) are the most widely used markers for forensic DNA testing.
DNA Research is the official journal of Kazusa DNA Research Institute, published by Oxford University Press and supported by funding from Chiba Prefecture, Japan.
DNA analysis, also called DNA typing or DNA profiling, examines DNA found in physical evidence such as blood, hair, and semen, and determines whether it can be matched to DNA taken from specific individuals. DNA analysis has become a common form of evidence in criminal trials.
Forensic scientists use DNA in blood, semen, skin, saliva or hair found at a crime scene to identify a matching DNA of an individual, such as a perpetrator. This process is called genetic fingerprinting, or more accurately, DNA profiling. Other uses include that in bioinformatics and nanotechnology.

Chapter 7: The New Genetics—Techniques for DNA Analysis Introduction Before the 1980s, finding the genotype of an individual usually involved various laboratory assays for a gene product—the protein or enzyme. The cases of the ABO and Rhesus blood groups are classic examples of how one infers genotypes from the reaction of gene products with certain chemicals. In the mid 1980s, genetic.
Data Analysis The amplification products for each DNA sample with primers were considered as polymorphic when they were present in some individual and not in others. The prominent DNA bands were scored visually on the basis of their presence (1) or absence (0) for all of the samples studied.
It’s been a long journey from the discovery of DNA and up to the sequence of genes. Therefore, writing a decent research paper on genetics is quite an adventure today. Note that choosing the right topic will reduce the difficulty of writing your research. Also, make sure that the topic has sufficient reliable resources before you start writing.

Nuclear DNA analysis being an exception, there is no other forensic method that has severely shown the capacity to persistently, with a high degree of assurance, exhibit a connection between a specific individual or source and the evidence. For instance, fingerprint analyses have more available research and conventional protocols than for bite marks analysis. There are also notable variations.View Recombinant DNA Technology Research Papers on Academia.edu for free.In fact, because DNA profiling and analysis did not exist until the 1980's, a reexamination of the evidence which was collected in older investigations often reveals DNA profile of the person that was convicted of a crime does not in any way match the DNA profile that exists from biological samples which were collected from the crime scene. This consequently means that the person is innocent.
