Historical Discoveries Of Dna And Genetic Material

When most people think of DNA, scientists, laboratories, and twisted ladders come to mind. In reality, DNA makes up genetic material, which makes up proteins that form much of the body and perform vital tasks. The study of DNA and genetic material is something more people should be aware of. As a society, knowing how powerful genetic research and technology are holds the possibility to help, or possibly hurt, people now and in the future. The study of deoxyribonucleic acid, better known as DNA, sounds modern, but in reality has been around for over 150 years. In 1856, Gregor Mendel performed his famous pea plant experiment. This experiment helped determine dominant and recessive traits. Mendel’s work faded for more than 30 years. Based on his research, Reginald Punnett developed Punnett Squares. Punnett Squares predict which traits offspring will inherit based on their parents. In 1885, scientists found chromosomes in cells. Even though there were many contributing factors, one of the most important discoveries about DNA was made by Francis Crick and James Watson. Francis Crick was born in 1916, in Northampton, England. Early in his life, he studied physics but later turned to biology. He attended University in London and earned his Ph.D in molecular biology in 1954. James Watson was born April 26, 1928, in Chicago, Illinois. He enrolled in the University of Chicago when he was just 15 years old. He earned his Ph.D. when he was 22 by completing studies on bacteriophages.Show MoreRelatedHistorical Discoveries Of Dna And Genetic Material1364 Words   |  6 Pagespeople think of DNA, scientists, laboratories, and twisted ladders come to mind.

One significant advancement is the discovery of Deoxyribonucleic Acid (DNA). The discovery of DNA has greatly enhanced our ability to analyze ancient remains and interpret the findings within the field of archeology. To fully demonstrate the impact that DNA has brought to the field of archeology it is important to understand the historical discovery of DNA and initial integration into the field of archeologyRead MoreThe Process Of Evolution And Evolution1679 Words   |  7 Pagesprocess by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth,† Google.

Little did Darwin know that his curiosity and ability to apply knowledge during this time in his life, would lead him to become a notable historical scientific icon still admirable today. It was due to this opportunity that his work transformed the 19th century scientific path by creating a new mindset of the development of earth (Appleman, 1970).

In this work he argued that before God’s existence can be debated, a definition of who or what God is has to be established. Today he calls this book ‘a historical relic’ (p.52) and uses the arguments for God in his debating for the Christian faith. The last book that I want to mention was published in 1971 and was called ‘The Presumption of Atheism.’ This was his final work in dealing with atheism, in whichRead MoreEthical and Legal Issues with DNA Profiling2693 Words   |  11 Pagesacidity (DNA) fingerprint scanning service is really a fundamental technique which is used all through the global communities every day. The procedure associated with DNA fingerprint scanning service was initially produced by the geneticist, Alec Jefferys, in the University of Leicester situated in England, in the year 1984 (as cited in Lampton, 1991). Both primary kinds of DNA utilized in the actual profiling procedure consist of mitochondrial as well as nuclear DNA (Adams, 2005).

Mendels paper was all but forgotten until 1890, when it was rediscovered and contributed to a growing wave of interest and research in genetics. But it was not immediately clear how to reconcile new findings about the mechanisms of inheritance with evolution through natural selection. Then, in the 1930s, a group of biologists demonstrated how the results of genetics research could both buttress and extend evolutionary
