Even though altering DNA can lead to such horrifying events as genocide or viral diseases‚ genetic engineering is an important scientific breakthrough because with genetic engineering‚ we can alter DNA molecules and by altering DNA‚ we can cure many diseases and solve many of mankind’s problems. The first step to understanding genetic engineering‚ and embracing its possibilities for society‚ is to obtain a rough knowledge base of its history and method. The basis for altering the evolutionary process

Figure 1: Recognizing the pattern of the "rabbit problem". If we were to keep going month by month‚ the sequence formed would be 1‚1‚2‚3‚5‚8‚13‚21 and so on. From here we notice that each new term is the sum of the previous two terms. The set of numbers is defined as the Fibonacci sequence. Mathematically speaking‚ this sequence is represented as: The Fibonacci sequence has a plethora of applications in art and in nature. One frequent finding in nature involves the use of an even more powerful

Mendelian Genetics Introduction In 1865 an Austrian monk‚ Gregor Mendel‚ presented the results of painstaking experiments on the inheritance of the garden pea. Those results were heard‚ but not understood‚ by Mendel’s audience. In 1866‚ Mendel published his results in an obscure German journal. The result of this was that Mendel’s work was ignored and forgotten. Mendel died in 1884 without knowing the pivotal role his work would play in founding the modern discipline of genetics. By 1899‚ some

3 is a number‚ numeral‚ and glyph. It is the natural number following 2 and preceding 4. In mathematics Three is approximately π when doing rapid engineering guesses or estimates. The same is true if one wants a rough-and-ready estimate of e‚ which is actually approximately 2.71828. Three is the first odd prime number‚ and the second smallest prime. It is both the first Fermat prime and the first Mersenne prime‚ the only number that is both‚ as well as the first lucky prime. However‚ it is

always been an interesting concept to me. A number that is infinitely being calculated seems almost unbelievable. This number has perplexed many for years and years‚ yet it is such an essential part of many peoples lives. It has become such a popular phenomenon that there is even a day named after it‚ March 14th (3/14) of every year! It is used to find the area or perimeter of circles‚ and used in our every day lives. Pi is used in things such as engineering and physics‚ to the ripples created when

activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases‚ the rate of enzymatic activity increases until the optimum
