The story The Structure of DNA: Cooperation and Competition demonstrates the nature of science in many ways. DNA was not discovered by just one person‚ it was discovered by many different scientist who built on each others’ ideas. The main scientists who were featured in the story were James Watson‚ Rosalind Franklin‚ Francis Crick‚ Raymond Gosling and Maurice Wilkins. In the case of this story‚ scientific knowledge assumes an order and consistency in natural systems. Science models were used

Forensic DNA Evidence DNA has become one of the most accurate tools used in law enforcement in determining guilt or innocence. DNA is different in all people it is our “genetic blueprint.” DNA is so significant to law enforcement because DNA left at a crime scene can be collected and tested to see if there is a match. It is unique because it ensures accuracy and fairness. The initial use of DNA began in Britain in 1986; the FBI used it for the first time in the United States two years

All rules regarding the formulation of questionnaire questions – no matter who has created them and where they are to be found – have one crucial disadvantage: they only have limited use. Of course‚ they are more or less suitable as “general guides” which can point you in a general direction‚ but their importance usually diminishes when it comes to formulating specific questions for specific questionnaires. It is then necessary to rethink each formulation and‚ while the rules regarding the formulation

known as restriction endonucleases) are a group of bacterial enzymes which cut double-stranded DNA (dsDNA) into smaller fragments at specific points. They are a defence mechanism used by bacteria to cleave the DNA of invading viruses‚ thereby restricting their expression. The exploitation of restriction enzymes ability to cut large pieces of DNA into smaller fragments (called restriction fragments) and the highly specific way in which they do this has played a crucial role in the exponential advancement

DNA fingerprinting is a way of identifying a specific individual‚ rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology‚ it has been around since at least 1985‚ when it was announced by its inventor‚ Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal
