Introduction Cells are the building blocks of the diverse idea we call life, which means that they must be as diverse as life as well. Prokaryotic and Eukaryotic cells make up most of the life on this planet, and vary widely in function, while still sharing some similarities. Prokaryotic cells, although simpler and smaller, make up most life. A nucleoid region contains a loop of nucleic acids known as a DNA plasmid. Prokaryotic cells contain simplified ribosomes which free float in cytoplasm…

Gene Therapy & Cancer Cells Gene therapy is often defined as a treatment that uses genes to cure or prevent diseases. Genes, DNA, and protein are all involved with each other, therefore, in many immune diseases, if one fails your whole immune system could eventually fail. This treatment is relatively new; hence it is still a pretty risky experimentation since it involves getting genes into cancer cells. Gene Therapy is often involved in serious cancer cell treatments; its main purpose is to try…

Our Actions and Their Consequences Have you ever wanted to change yourself? You may want to rethink that. During the short story “Flowers for Algernon” by Daniel Keyes, Charlie undergoes a experimental surgery to increase his intelligence. The story is a collection of all of Charlie’s progress reports from before to after his surgery. He continually writes better and with more intellect, and then he begins to decline. He gets amnesia and other terrible symptoms, such as depression, and…

external modifications to DNA that turn genes “on” and “off”. Although modifications don’t change the sequence per se, it changes the way the cells “read” genes. Essentially, this is what differentiates genetics from epigenetics. Going further into detail, genetics conceptually deal with gene and gene function. This focuses on how DNA sequences make changes in the cell. However, epigenetics refers to gene regulation. Instead, it focuses on the way DNA is regulated to attain those changes. …

Deciding Actively Listening for the Public Voice, by Robert Cook-Deegan and Jane Maienschein, discusses the issue of genetic engineering and the ethical dilemma and how the United States, government, and people are interacting in the struggle of the ethics behind genetic engineering. The authors present the facts that genetic engineering has laid in the grey area ever since it was first brought to in lab, and still continues to sit in that grey area. Genetic Engineering will occasionally pop up…

Fundamentals of Biochemistry in the Biotech Industry Maple Syrup Urine Disease: A Sweet Scented Killer Maple Syrup Urine Disease (MSUD) is a rare, potentially deadly disorder where the body cannot break down the three branched- chained amino acids (BCCA): leucine, isoleucine and valine. These amino acids are used to build proteins and when they are not being used they can be broken down and recycled in the cell. The complex that breaks these amino acids down is called BCKD (branched-chain…

Ordinarily, multicellularity means a condition or state of having or being composed of many cells or more than one cell performing differing functions. A multicellular organism should have cells that contain the same genetic information. Until now, information regarding multicellularity is still a mystery because the ability to go further is still not that sufficient. The reasons behind this lack of background are the “long ago” divergence from the common unicellular ancestor of the organisms…

genetically similar to the original organism. Cloning can also be applied to cells. The first mammal that was cloned successfully from an adult cell was the sheep named Dolly in the year 1996 by Scottish scientists in the Roslin Institute. Importance of Cloning and how it is being used: Cloning allows scientists to find out about what proteins are present and what they do and also allows them to find out what happens in the cell when the protein is changed. Cloning also…

Critical Reaction #10: “Gattaca” Movie Summary In the not too distant future where genetic engineering in humans is common and DNA determines a person's social class. Vincent is conceived and born without the aid of this technology. Dealing with the nearly demolished physical dysfunctions of heart problems, as well as having a short life expectancy. The only way he can achieve his lifelong dream of going to space is to break the law and act as a "valid" person with appropriate genetic code.…

Various prominent cells of the motive are articulated, particularly the interval of the major 3rd, which is passed around in various registers. At 2:19 a cell of the motive is used as an accompaniment figure in the L.H. At 3:35 the fuller melody returns in several tessituras. At 3:56 a small apotheosis of the theme occurs. At 6:23 a key…
