Side By Side Endoplasmic Reticulum
2,193 words... e detoxification processes by which enzymes act on chemicals and drugs to change their structure and reduce their toxicity. The smooth endoplasmic reticulum of skeletal muscle stores calcium ions that function in muscle contraction. The Golgi apparatus is composed of flattened membranous sacs, containing cisternae, that are stacked on each other like dinner plates. The Golgi apparatus modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic ret...

Cloning Animals Cloning Technology
977 wordsIntroduction Todays technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell ...

Sense Of Individuality Organ Transplants
1,080 wordsA clone is the name given for a group of organisms or other living matter with exactly the same genetic material. Genetic material consists of genes, which are the parts of cells that determine all characteristics of living things. It is not until recently that scientists have developed an experimental process for cloning higher animals, such as humans. This is a very technical process which involves first destroying the nucleus of an egg cell from the species to be cloned. Then a nucleus is rem...

Genetically Identical Ethical Questions
583 wordsCloning is producing a genetically identical organism to its parent. Since 1997, there have been many examples of cloning. Two examples are of Dolly the sheep and Tetra the monkey. These two clones are examples of different techniques used for cloning. And because of the previous two examples of cloning many ethical questions have been raised. In 1997, Scottish scientist Ian Wilmut and his workers produced a sheep named Dolly. What was so great about Dolly? Dolly was a clone. She was made from a...

Cloning Of Animals Enucleated Egg
967 wordsWhat is a Clone? A clone is a group of genetically identical cells. For example, tumors are clones of cells inside an organism because they consist of many replicas of one mutated cell. Another type of clone occurs inside a cell. Such a clone is made up of groups of identical structures that contain genetic material, such as mitochondria and chloroplasts. Some of these structures, called plasmids, are found in some bacteria and yeasts. Techniques of genetic engineering enable scientists to combi...

2,305 wordsCataracts In Cataracts Cataracts 2 Cataracts In Elderly Introduction What is a cataract? A cataract is a cloudy or opaque area in the normally transparent lens of the eye. Its effect on vision depends on the extent of the cloudiness. Small spots in the lens may cause little or no vision loss. As the opacity thickens, it prevents light rays from passing through the lens and focusing on the retina, the light sensitive tissue lining the back of the eye. Early lens changes or opacities may not distu...

Egg Cell Closely Related
944 wordsCloning Technologies and More Science, in the past few years has made great strides in the field of mammal reproduction. They? ve worked for years to find out exactly what happens during a pregnancy, and also how it works. We? ve come so far in these stages as to gain the knowledge needed to make oral contraceptives. However, I am not writing this report to enlighten you on these subjects, or to debate the ethical issues of them. This report is focusing on the creation of life, not the destructi...

Vitro Fertilization Genetically Identical
1,266 wordsCloning, Cloning Clones Clones Cloning, the process of creating a copy of a plant or animal that is genetically identical to the original through asexual means, has sparked some interesting moral and ethical debate. For years, cloning has been used to produce a greater number of a specific type of plant, such as the Macintosh apple trees, which have all been derived from single mutated plant. Now, however, upon the discovery of a method to clone animals, even humans, people are beginning to beco...

Vitro Fertilization Fertilized Egg
871 wordsTo clone or not to clone, that is the question. If Shakespeare were alive today, he might well have used this phrase instead of the one he chose for his play Hamlet. The question is an important one because Dr. Ian Wilmut, an embryologist from Scotland, recently stunned the world by declaring that he had cloned a lamb from the DNA of a ewe. Since the technique he used may possibly be reproduced to clone a human someday, the public outcry has been considerable, as has the question of whether our ...

Are researchers taking many unnecessary risks with all the unknown affects it could bring to the human clone and the ethics of our society today? The term clone refers to a group of organisms that are genetically identical. Most such clones result from asexual reproduction, a process in which a new organism develops from only one parent (World Book Encyclopedia). To give you a little history of cloning, it began a lo...

Process Of Cloning Real Person
927 wordsA clone is a group of organisms that are genetically identical. Most clones result from asexual reproduction, a process in which a new organism develops from only one parent. The one process of cloning, called nuclear transfer, replaces the nucleus of an immature egg with a nucleus from another cell. Most of the work with clones is done from cultures. An embryo has about thirty or forty usable cells but a culture features an almost endless supply. When the nucleus has been inserted into the egg ...

3,365 wordsDNA Deoxyribonucleic Acid the material that codes for amino acids which form proteins, which in turn carry out functions of the cell. DNA is responsible for building life. Our physical characteristics, susceptibility to some diseases and disorders (e. g. breast cancer, sickle cell anemia), and a few behavior characteristics are passed from generation to generation through DNA. DNA controls everything about the way we look, from the color of the eyes to how tall you are to the width of your feet....

1,451 wordsDeoxyribonucleic acid and DNA DNA 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. (Miller, 139) DNA is the genet...

Gene Therapy Germ Cells
1,087 wordsHow does gene therapy work? All life contains genetic information in the form of DNA. DNA can be reproduced and passed on to subsequent generations. A gene is a stretch of DNA that contains the blueprint for the sequence of amino acids making up a particular protein. Proteins are vital because they are used in catalyzing various biochemical reactions, they act as messengers, they regulate cell growth, development and reproduction, transport oxygen in the blood and are a defense against diseases....

Big Bang Theory Hydrogen Ions
3,468 wordsLuminosity is the amount of light that is radiated from a star. White light is the composition of all colors. In elements, the energy discharge can be displayed as light. Just by looking at the colors that are discharged, one may precisely identify the element. In understanding the universe, the Doppler effect is one of the most important tools. The Doppler effect is a shift in frequency due to a moving source. Skipping a rock on water would be an example of this effect. The circles would be off...

Even a cell, the smallest form of life known is extremely complex. All life begins as a single cell. I can not begin to understand the depth of what it takes for one cell to multiply and change until we become conscious of ourselves. There are two types of cell division, Meiosis and Mitosis. Meiosis is...

At the time, I didn t quite realize that quantum theory and quantum physics were related except in name. Niels Bohr once said, Anyone who is not shocked by quantum theory has not understood it. He believed this because quantum physics makes the common laws of classical physics false on small scales. First, quantum physics is the physics of the incredibly small. It tries to explain the ...
