structure of DNA James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin What did they discover about DNA? James Watson, along with Francis Crick, studied the molecular structure of DNA that had been extracted from cells and showed how it could serve as the chemical basis of inheritance. Although it is commonly known that everything they "discovered" they stole from Rosalind Franklin, who proceeded to obligingly die. That said they're incorrectly famous for discovering that DNA is composed

Let us say something about Energy that I know while I was in high school Physics class. Energy is usually defined as the ability to do work. In general; we would say that energy is fundamental entity whose availability and flow are required for all phenomena, natural or artificial. Energy neither be created nor destroyed; rather it is changed from one form to another. That means mechanical energy, such as the kinetic energy of motion can be converted to heat energy. Let’s come to the type of energy

Classification of viruses Student name Course Institution Instructor Date due Classification of Viruses Most things living things in our world are classified into five different categories. Scientist, biologist and academics do this so they know the exact organism that is being examined and discussed. The five kingdoms of life are identified as: plant, fungi, animal, moneran and fungus. Although, in my research

Unit 12 M1- Compare historical and current features of Public Health. In this part of the assessment I am going to compare elements of historical Public health to the elements of today. By looking at my timeline presented in P2 I am going to research and compare these elements to those of today. Them concluding the overall comparison of the both. In the 19th century public health was less of a function of government and instead it was a function of charitable organizations and volunteers. These

When one thinks of cloning they make think back to a science fiction movie they saw where clones took over the world or a book of the same genre where clones did something evil. Cloning has always been looked at as a futuristic endeavor, but truth is that cloning is here already. The most famous case of cloning is with Dolly the Sheep, which was the first animal to be cloned from a somatic cell. With cloning comes a wide variety of potential for science, some of which include organ transplantations

called organelles. These organelles are the structural and functional units and are created from several macromolecules connected together. A typical animal cell contains the following organelles (Tracey Greenwood, 2012): the nucleus (which houses the DNA), mitochondria (which produce energy), ribosomes (which make protein), the endoplasmic reticulum (for transportation) and the golgi apparatus (which distributes
