DNA FINGERPRINTING Name University DNA FINGERPRINTING DNA which is the Deoxyribonucleic acid is basically a chemical structure that makes chromosomes, one piece of chromosome which shows one specific trait is known as gene. DNA is basically double helix and it is made up of two strands of genetic material which is spiraled around one another .Chemically DNA structure of everyone is the same however the order of base pairs differs in human beings and animals…

Extract of sample "DNA fingerprinting"

Download file to see previous pages It helps in identification of an identity with full confirmation (Brinton, K., & Lieberman, K).Scientists use the unique markers, match them up in order to form a permanent fingerprint. It is useful in obtaining the identification needs and it also helps in providing information in case of missing people. We can find out through the samples that they belong to one person, related people or non related people. There are various forms of DNA fingerprinting which includes Southern Blot, through which scientists analyze the genetic pattern which is a part of a person’s DNA. In it the isolation of DNA from rest of the cellular material is done followed by cutting the DNA into several pieces and then gel electrophoresis is done and finally the blotting of the DNA is done (National Health Museum). Another kind of fingerprinting includes Restriction fragment polymorphism which analyzes the lengths of the strands of DNA. Polymerase chain reaction was used in laboratories for hereditary authentication. Amplified fragment length polymorphism is also an important kind of fingerprinting. The most widely used kind of DNA fingerprinting is the short tandem repeat method which helps in extracting the DNA. ADVANTAGES AND APPLICATION OF DNA FINGERPRINTING: DNA fingerprinting helps in determining Paternity and maternity, as a person inherits the VNTRS from his mother and father that’s why it helps in finding biological parents. It also helps in finding personal identification. the fingerprints which are formed from the genetic bar codes helps in identifying individuals. It is very important in criminal suspects and criminal identifications. DNA material which is from blood, hair, skin cells and other genetic proofs are available at the crime scene. These DNA fingerprinting is thus helpful in finding the criminals, guilty people and the innocent people. DNA fingerprinting also helps in testing for the ethnicity. Overall the tests are very helpful in finding deceased people identification (Benefits & Limites of DNA Fingerprinting) It is a very helpful method in finding bodies and identifications of soldiers who are killed in wars. It also helps in finding inherited disorders in new born babies and prenatal babies. DISADVANTAGES OF DNA FINGERPRINTING: Fingerprinting process requires proper quality control methods and regulations along with proper standardization in order for it to be accepted universally. There are not many places and labs which can conduct the DNA fingerprinting process well, overall there are only few proper labs who can provide accurate results for DNA fingerprinting. The probability of DNA sequence of being similar is just one in 50 billion which is extremely low. There is also a problem of population genetics as the genetic inheritance are not distributed evenly and they are not the same overall across the human beings. There are few technical difficulties as well in DNA fingerprinting process, It required to be run on various samples and twice. There is another important disadvantage of threat of the results being used for privacy concerns. Complete confidentiality is required and the information should not be shared with anyone except the owner. REFERENCES: Benefits & Limites ...Download file to see next pagesRead More

Discuss and analyze DNA and fingerprinting technologies used in law enforcement today

...? DNA and fingerprinting technologies used in law enforcement today DNA and fingerprinting technologies used in law enforcement today Current criminals are smarter than the criminals in the past and they have the ability to conduct crimes without leaving any evidences at the crime site. However, science and technology developed a lot and new methods of gathering evidences were implemented in crime investigations. DNA and finger print technologies are helping investigating officers immensely at present in establishing crimes in the court. This paper analyses the effectiveness or potential effectiveness and drawbacks of these new technologies. No two...

DNA Fingerprinting

...DNA Fingerprinting DNA fingerprinting is a laboratory procedure that has proved very useful in personal identification. With its wide applications, it is causing a revolution in the modern world. Typing of DNA presents unique profiles for each individual except identical twins. The high rate of variation results because DNA fingerprinting relies on non-coding hyper-variable sequences to produce a unique pattern of bands for each individual. DNA profiling relies on the discovery of a broad range of restriction enzymes and their specificity. DNA typing has a wide range of applications from...

DNA Fingerprinting

...DNA Fingerprinting Introduction DNA as we all know is the basic building structure of every living thing present on earth. It has been scientifically proved that it is the DNA that gives us our characters, both phenotypic and genotypic. If the there is some sort of problem i.e. mutation in the DNA, it would lead to altered characters or even lead to abnormalities (Burke 1991). The DNA sequence of every individual is specific and is generally passed on from parents to their offspring. The basic structure of a DNA consists of four Nucleotide bases i.e. Adenine, Thymine, Guanine and Cytosine. These four bases pair with each...

DNA Fingerprinting in Molecular Biology

... DNA FINGERPRINTING IN MOLECULAR BIOLOGY Although a novice in the scientific fields, DNA fingerprinting became one of the fastest known and adapted genetic technologies in the world. The applications of this field are very large, and its legal and ethical percepts too. This is the technology of the future and will improve constantly with time. The complexity of the technology makes it hard to fathom how Sir Alec Jeffreys was able to discover it in the early 1970s. This was the time when scientific technologies were still in their beginner stages, and it was until 20 or so years later that any real inventions and revolutions were to take place in DNA technologies. Jeffreys began at the simplest, by detecting single copies... house...

...,” but the court “deemed this question to be irrelevant because evidence need not be scientific in order to be admissible - it could be based on technical knowledge” (Cole, 2001, p. 285). The legal challenges that fingerprint identification will endure are far from over. Some fingerprint skeptics feel that fingerprint identification will eventually be considered obsolete and DNAfingerprinting” will be the new standard of identification. Professor Andre Moenssens (2002) argued the difference between the two sciences, stating that, “fingerprint identification does not rest, as does DNA analysis, on class characteristics,...

Fingerprinting Paper

...Fingerprinting Paper Fingerprinting Paper Question Q1. Are there any current or potential alternatives to traditional fingerprintingthat would better aid in solving crimes? In the brief history of biological identification of persons, fingerprinting has been the traditional classic of personal identification. Nevertheless, fingerprinting thrived in an analogue world where there was very little else to resort to, which had any technological advantage. In the era of digital technology and PINs (Personal International Identification numbers), there are extensive possibilities that would either complement or replace the fingerprint (Chandos & Piosenka, 1991;...
