The world today seems to be going crazy: The Unabomber's Manifesto It was May 25th 1978, Terry Marker was on his usual patrol on campus at the University of Illinois. This earmark package, addressed to an engineering professor at Rensselaer from a material science professor at Northwestern, was found in a parking lot. What seemed like an insignificant misplaced parcel was about to start a reign of terror and the longest manhunt in U.S. history. Officer Marker retrieved the package and began to
Mitosis
Mitosis
Mitosis Cells can divide, and in unicellular organisms, this makes more organisms. In multicellular organisms, cell division is used for growth, development, and repair of the organism. Cell division is controlled by DNA, but exact copies of the DNA must be given to the daughter cells (note use of “mother” and “daughter”). Bacteria reproduce by a simple process called binary fission. They have one chromosome which is attached to the cell membrane. This chromosome replicates, then the two copies

The Human Genome Project
The Human Genome Project Walter Gilbert who is a molecular biologist became interested in undertaking the Human Genome Project (HGP) in 1987. Robert Kanigel of the New York Times Magazine wrote This project ... would reveal the precise biochemical makeup of the entire genetic material, or genome, of a human being ... it would grant insight into human biology previously held only by god.” (McMurry, 758) The plan was to create a map or library of human deoxyribonucleic acid (DNA). About the same

Basics of Genetics and Genetic Engineering
Basics of Genetics and Genetic Engineering my name my teacher,the hour June 5, 1996 Genetics is the study of how physical, biochemical, and behavioral traits are transmitted from parents to their offspring. The science of genetics started in 1900, when the work of Gregor Mendel was discovered. Mendel described the inheritence patterns of garden peas. He suggested after researching his pea-plant experiment that each parent has pairs of units but contributes only one unit for to each pair of its

Xeroderma Pigmentosum is a very rare genetic defect affecting less than 1,000 people known worldwide. XP is a rare genetic defect in ultraviolet radiation induced DNA repair mechanisms and is life threatening because the DNA damage is cumulative and irreversible. This defect is characterized by severe sensitivity to all sources of UV radiation, specifically to sunlight. The wide range of symptoms include blindness and deafness, blistering or freckling on minimum sun exposure, dwarfism and hyper

How We Evolved into Homo Sapiens
How We Evolved into Homo Sapiens Uneducated people who believe in evolution have a pretty vague idea of what caused the human race to have the appearance it has today. There is more to the story of human evolution than saying that primitive monkeys somehow evolved into brutish Neanderthals, learned to use fire, made up a common language, and eventually became modern humans. It is a long story of species who endure set backs and breakthroughs in evolving for survival. The dawn of apes is recorded

The theory of evolution as set forth by Charles Darwin in 1859 stated
The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thought that the few missing

AIDS AND IMMUNITY Battling the Perfect Immune System Killer It's hard to tell if the glass is half full or half empty, Ilana Fogelman said, shrugging her shoulders. She was speaking of her Food and Drug Administration research on the immune responses of AIDS patients who have been taking the powerful triple-drug combination therapy called HAART. Pointing to her work, posted on a wall at the 12th World Conference on AIDS here, she knitted her brow and then concluded, We'll have to do some more

The transformation time from tree-shrew, to ape, to human far exceeds the time from analytical engine, to calculator, to computer. But science, in the past, has always remained distant. It has allowed for advances in production, transportation, and even entertainment, but never in history will science be able to so deeply aff

Genetic Modified Food
Genetic Modified Food Genetic modification of organisms in general is a biotechnological process that forces genes to behave according to certain characteristics. Changing characteristics of organisms is based on changing their DNA (tech deoxyribonucleic acid; the acid which carries genetic information in a cell). It is being used for modifying genes in plants, animals or micro-organisms. It is being also used especially with food in order to improve the nutritious quality, make less use of chem

The Future of Human Evolution Alexander R. Prof. Kohn Darwinism and Evolution 12-6-96 Evolution, the science of how populations of living organisms change over time in response to their environment, is the central unifying theme in biology today. Evolution was first explored in its semi-modern form in Charles Darwin 's 1859 book, Origin of Species by means of Natural Selection. In this book, Darwin laid out a strong argument for evolution. He postulated that all species have a common ancestor fr

Genetic Engineering The engineering of deoxyribonucleic acid (DNA) is entirely new, yet genetics, as a field of science, has fascinated mankind for over 2,000 years. Man has always tried to bend nature around his will through selective breeding and other forms of practical genetics. Today, scientists have a greater understanding of genetics and its role in living organisms. Unfortunately, some people are trying to stop further studies in genetics, but the research being conducted today will serv

Murder, Rape, and DNA Jonathan Dewees February 16, 1997 DNA is the information needed by a cell in order to reproduce an identical offspring. In some crimes detectives have no evidence or fingerprints to tell who had committed a crime. Now there is a way of finding who has committed the crime by a method called DNA Typing. DNA Typing is finding bacteria or blood on clothing or skin and amplifying the gene. This process was pioneered in the 1980's by a Scientist named Alec Jeffreys. If blood, spe

Introduction To Evolution
Introduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar

An End To Genetic Diseases
An End To Genetic Diseases The United States has a very diverse heritage. There is no American race. Americans are the blending of many cultures throughout many generations. With this blending of cultures comes a blending of genes. In the past, genes have not been well understood. They were not understood until Mendel did experiments on plants to find out why different plants of the same species had different characteristics. His goal was to find the key to unlock the mystery of inheritance (Cop

Cloning
Cloning Cloning, the process of “Manipulating a cell from an animal so that it grows into an exact duplicate of that animal is the forbidden fruit of biology.” (Begley 54). The word “clone”, derived from the Greek word “Klon”, meaning twig or slip, refers to asexual reproduction. Also known as vegetative reproduction. Cloning became known to the public about 30 years ago. This idea of cloning about his time resulted in an experiment of the successful asexual reproduction. This experiment took pl
