  • Nitrogenous Bases Amino Acids
    999 words
    Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20 th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cel...

    ... slightly negative and the other end of it is slightly positive. The Dispersion forces exist between non-polar molecules. Dispersion forces are another of van der Waals' three forces. They exist between non-polar molecules. It is important to remember that within a bond, electrons are constantly MOVING. They zoom around the atoms really quickly. As a result, there may be a tiny instant in that time span where the electrons happen to dominant on one side, rather than the other. However, this t...

  • Mad Cow Disease Amino Acids
    1,495 words
    Who would of thought that eating hamburgers, steaks and drinking milk could produce an epidemic disease? These types of food are frequently eaten for their appealing tastes and nutritional values. The discovery of Creutzfeld Jakob Disease (CJD) has been a long and remarkable one. The cause of this disease is a mutated prion protein within the brain that can be either inherited or acquired. These mutations create sponge like holes that destroy the brain. As a result, the disorder gives both behav...

  • Life On Earth H 2 O
    726 words
    The first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

  • The Biological Importance Of Water
    1,055 words
    Generally, the main biological importance of water is that life cannot exist without it. In fact on a percentage basis, the majority of any organism is comprised of water. Additionally, it is believed that life first originated in the bodies of water on the earth. The importance of water is seen in such third world countries as Kenya. Where the inhabitants are forced to drink water so dirty and contaminated that they know it might kill them. However they still drink it because its essential for ...

    Properties of Water Water is essential for life as we know it on earth. It is used by plants and animals for basic biological processes which would be impossible without the use of water. The origin of all life can be traced back to the water in the Earths precambrian seas. Water is also the universal solvent. It reacts with more elements and compounds than any other substance known to man. Water is a polar molecule made up of on atom of hydrogen and two atoms of oxygen. It is attracted to itsel...

  • Surface Of The Water Hydrogen Bonds
    984 words
    Water is the most important substance in our evolution and our daily lives. Without water, life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earths thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive one 1 (f...

    What properties of water make it a unique material and an essential component of living matter? Water is so common that it is easy to overlook the fact that it is an exceptional substance with many amazing qualities. With its properties, we can trace water s unique behavior to the structure and interactions of its molecules. Water is constructed of two hydrogen (H) and one oxygen (O). The hydrogen become + charged and the oxygen maintains a charge when they combine to form water. This is a singl...

  • Sickle Cell Anemia Red Blood Cells
    1,616 words
    Protein Synthesis The Expression of a Gene The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usable chemical energy. The cell c...

  • Protein Synthesis Amino Acids
    788 words
    Protein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structure. Once someone unders...
