Dna Discovery Is The Most Important Scientific Discovery...

DNA discovery is the most important scientific discovery of 20th century which increased our knowledge about hereditary material as the basis of life. It is present in all organisms from microscopic organisms like bacterium to macroscopic organisms like whale. It not only determines the physical characteristics of the organisms but the diseases develop in them. Deoxyribo nucleic acid is discovered by the decades of efforts made by the scientists. The history of the discovery of structure of DNA started in 1953 when Watson and crick discovered the structure of DNA. It is the blue print of life. It is a code and means of storing genetic information. It is a common misbelief that DNA was first discovered by Watson and Crick in 1953, but it was identified by a Swiss chemist Friedrich Meischer in 1869, not acknowledged much for his identification. But later on the Watson and Crick model of DNA was widely accepted and recognized. Meischer identified a substance while working on white blood cells of pus coated bandages. He used salt solution to find out the composition of WBCs. He noticed that a substance is separated from solution when he added salt in it. After that when he added alkali in it, the separated substance dissolved in it again. Meischer named this substance as â€Å"nuclein† .He discovered the hereditary material but unfortunately could not convince the scientific community about his findings. For many years scientists believed that protein is a substance which has storedShow MoreRelatedThe Discoveries Of The Discovery Of Dna957 Words   |  4 PagesThe discovery of DNA is arguably one of the most important brea kthroughs of genetics in the 19th and 20th centuries. Its discovery is littered with successes, failures, and even heartache. Numerous scientists are attributed to the discovery of DNA as a genetic material and even many more are also credited to the discovery of the molecule, structure, and function. Without the work of these remarkable scientists, the medical advancements over the last 50 years would not be possible. In 1865Read MoreHow Heredity Is The Passing Of Characteristics From One Generation1294 Words   |  6 PagesJames Watson and Francis Crick used the results of all these scientist to discover the meaning of life which was the structure of DNA. FREDERICK GRIFFITH ( 1877 - 1941) Frederick Griffiths was a british bacteriologist scientist who was born in 1877. Griffiths worked for the local government between 1913 till 1918 during world war 1. Living in this period it was important he could do a lot with very few basic apparatus. ( J. Stein Carter, 2000). Griffiths was searching for a vaccine against SpanishRead MoreMen and Women were Created Equal Essay examples751 Words   |  4 Pageshumanity impacted the whole world. Only in the 20th century, and most recently in the last 20 years, have women overcome social barriers and been allowed to obtain a scientific education. Today, women are becoming an ever-increasing percentage of the scientific and medical work force. In 1982 Barbara McClintock won the Nobel Prize for her discovery of mobile genetic elements. Her discovery was that genes could jump around on chromosomes. This discovery was the basis of today’s advances in genetic engineeringRead MoreMen and Women Were Created Equ Essay759 Words   |  4 Pageshumanity impacted the whole world.

Knowing the history can lead to even more discoveries in the future. When you think of anatomy you imagine something like this picture below. But here is where it all began†¦. The beginning of anatomy and physiology, ironically, began with a curiosity in biology. The first man to create an important contribution to biology was Alcmaeon, in the 5th century, BC. He was the first scientist to have worked with dissection. His focus was in trying toRead MoreThe System Of Science And The Law1069 Words   |  5 Pagesnatural world.

Q.2 What type of incident was the most important in driving the initial development of forensic science? Ans. The incident that acted as a driving force in the development of forensic science was the discovery of Locard’s exchange principal which was evolved from his studies and work.

Before the DNA double helix was discovered two biological question were unanswered: how can information for specifying an organism be carried in chemical form? and how is it accurately copied? It was not until the 20th century when the DNA molecule was discovered and suggested answers to both these questions. (Alberts B, Johnson A, Lewis J, et al, 2002) With the help of many scientists we now know exactly what the DNA molecule is, its structure, and its functionRead MoreA Little Big Research of Sun Tanning998 Words   |  4 Pagesthe global culture for a long time. In this paper, I would like to examine the roots and the reasons of tanning, the attitudes people have had towards it t hroughout the time, the effects on health, and the cultural differences of today. The most important thing one needs to be able to tan is, undoubtedly, sun. The Sun formed about 4.567 years ago along with the solar system from the gravitational collapse of a region within a large molecular cloud.
