Nasopharyngeal Carcinoma was first documented in 1901 and described clinically in 1921. (We I* et al.2007). The malignancy continued to evolve reaching a global death rate of 50,800 deaths in 2012. The epidemiology is still perplexing. Worldwide it is an uncommon tumour. Nevertheless, in certain regions such as China, NPC occur with a drastically high…

Over 50% of the dry weight of organisms are made of proteins; this is because things like your nails and hair are made of proteins. Proteins are also components of biological membranes, and they help regulate the passage of molecules through the membranes. This is all very important to the body, but the most important…

Twenty-five years ago, scientists thought that cloning was virtually impossible. In the last five years, the science of cloning, has come to realization. What is a clone? A clone is a duplicate – much like a photocopy is a duplicate, or copy, of a document (Kolate, 238). A good example of copies that occur in…

Many people believe in it, while at the same time, many don’t. Like it or not there are many factors that point to the existence of evolution, but what role does evolution play in the theory of learning. It is obvious that learning has an important bearing on evolution. Ideas or actions that are advantageous…

The sea anemones that were collected for the “Clone Specific Segregation in the Sea Anemone Anthopleura elegantissima” experiment were collected by Lisbeth Francis in Pacific Grove, California. The topic of Franciss report is the particularity of the constant anemone-free areas dividing contiguous accumulations of these anemones and the connection of these areas to the dispersion…

Intelligence is most commonly though of as quickness of understanding or mental power and ability the testing this capacity in education or for a job interview. Conversely, Garrett (1947) proposes that the higher test performance by the white race is an indication of a superior genetic intelligence. Additionally, Jensen (1969) suggested that the test differences…

To put a definition plainly, teratogens are agents responsible for countless birth defects. Research found suggests over eight hundred known teratogens. In this paper, you will find interesting facts based on research, the relationship between teratogens and developmental psychology and some personal views based on the information and research found for this piece. Teratogens are…

Skin Cancer Each year more than 600,000 people learn that they have some form of skin cancer. (National Cancer Institute. Skin cancer is the most common type of cancer in the United States. It is estimated that 40 to 50 percent of Americans that live to the age of 65 will have skin cancer at…

Using a 40cm piece of string, make another circle inside the cell to represent the nuclear membrane. o Fold each of four strips of paper in half, lengthwise. Then place one strip of each color inside the nucleus to represent a chromosome before replication. The light and dark strips of the same color represent homologous…

Structure DNA and RNA are nucleic acids. Nucleic acids consists of minor particles called nucleotides. In DNA and RNA, these nucleotides contain four nucleobases —nitrogenous bases or bases — two purine and two pyrimidine bases. DNA is found in the center of a cell (atomic DNA). It has two nucleotide strands which comprise of its…
