The discovery of DNA is attributed to the research of three scientists in 1951; Francis Crick‚ Maurice Wilkins‚ and James Dewey Watson. They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals

Anatomy of Hearing including Ear Structures and Brain Structures The ear‚ an organ for hearing and balance‚ is anatomically divided into three sections: the outer ear‚ the middle ear‚ and the inner ear (Henderson). Each section contains many distinct parts that assist in the task of detecting and interpreting sound which is otherwise known as hearing (Henderson). The outer ear is composed of the auricle (pinna) and the external auditory canal (ear canal) (Sisco). The outer ear functions to

In a more restricted sense‚ a scientist is an individual who uses thescientific method.[1] The person may be an expert in one or more areas of science.[2] This article focuses on the more restricted use of the word. Scientists perform research toward a more comprehensive understanding of nature‚ including physical‚ mathematical and social realms. Philosophy can

there has been much debate as to whether it is a mammal and how it should be classified. The platypus is a primitive mammal that has many features that separate it from other mammals-it lays eggs‚ there is an absence of true teeth and an absence of mammary glands‚ although it has special glands that secrete milk. It has fur like other animals‚ but it has a beak like the bill of a duck‚ webbed feet and a tail like a beaver. A dried platypus skin has been sent to England in 1798 and was considered to

DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA)‚ but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). The order‚ or sequence‚ of

DNA REPLICATION WHAT IS DNA? DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A)‚ Guanine (G)‚ Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose. THE PROCESS OF DNA REPLICATION How DNA replicates is quite a simple process. First‚ a DNA molecule is "unzipped". In other words‚ it

Who Discovered DNA? Heather Kane The discovery of deoxyribonucleic acid‚ more commonly known as DNA‚ has been the foundation for much scientific work. This fundamental discovery was credited to James Watson and Francis Crick. Many people believe that another person‚ Rosalind Franklin‚ also played a large role in the research. How much did she contribute to the discovery? Why is her name left unrecognized? This paper will discuss her part in the search and whether her name should appear next to
