Gene therapy

Gene therapy is the use of genes and the techniques of genetic engineering in the treatment of a genetic disorder or chronic disease. Most of the techniques are still being experimented and are awaiting government approval (Concise Columbia Electronics Encyclopedia). Some 2000 to 3000 diseases have been determined as genetic or hereditary (Access Excellence). With the perfection of gene therapy thousands of lives could be spared. Gene therapy may eventually provide effective treatment for many diseases that currently have no cure: muscular dystrophy, diabetes, cancer, and even acquired immune deficiency…

Human Genome Project

Human Genome Project, international scientific collaboration, the goal of which is to gain a basic understanding of the entire genetic content, or genome, of a human being (see Genetics; Heredity). This genetic information is found in each cell of the body, encoded in the chemical deoxyribonucleic acid (DNA). The project is intended to identify all the genes in the nucleus of a human cell; to establish, by a process known as mapping, where those genes are located on the chromosomes in the nucleus; and to determine, by a process known…

The Human Genome Project

What would you do if you were given the power to change your genetic code from brown hair to blond?. Man has had this ability through natural selection for some time without knowing it, but in the near future scientist will be able to speed the process of natural selection by changing a persons genes. Scientists have identified what constitutes human DNA located in the nucleus of a cell. The Human Genome Project was established to identify the genes that make us who we are and is now an international…

Genetic Manipulation Yes or No

Genes, being part of the basic building blocks of man, control all aspects of one’s life. They control how tall you are, what color your eyes are, and what diseases might afflict you in the future. Therefore, the manipulation of such genes can be a controversial topic. The controversy most likely stems from the ethical and social questions that are raised by this procedure. Jean Dausset, author of “Scientific Knowledge and Human Dignity,” and George B. Kutukdjian, author of “UNESCO and Bioethics,” both discuss the topic of genetic manipulation. Their…

The Right to Know Genetic Information

After forthy-seven year old Mimi Joling found out her forty-eight year old sister was diagnosed with breast cancer, she decided to get genetically tested. Joling wanted to know more about her risks and the options available to help prevent herself from getting cancer. “I thought for sure that I would be negative. But then, when I found out I tested positive for the gene mutation, I was totally shocked. I started crying, and it was really emotional,” Joling remembers. After finding out her diagnosis she attended a two hour long…

Genetic Observations Through The Studies Of Hybrid Corn, Single Gene

The basic foundation of modern genetics was led by Gregor Mendel (Corcos, 1993). Mendel was not the first to experiment with heredity, and our Lyman Briggs biology class will not be the last to deal with genetics. Genetics is the science of heredity. In our lab, we had three main objectives. First, we evaluated our data on monohybrid and dihybrid corn cross seed counts against Mendel’s theoretical expectations of independent assortment and the segregation of alleles. Next, we used the Hardy-Weinberg Theorem to provide a theoretically expected value for allele…

Genetically Engineeres cropsanimals

Genetically engineered crops/animals Man has been changing the genetic make-up of plants and animals, in a limited way, for thousands of years–ever since he look to planting seed from those wild grasses that gave the most grain and were easiest to harvest, or started keeping his fattest Cattle and woolliest sheep to breed from. We’ve come a long way since then, and today’s sophisticated breeding techniques have led to such break-through as high-yielding rice and dwarf wheat. Despite our advances though, our ability to Create new plants and animals is…

Genetic screening

Genetic screening, also known as preimplantation genetic diagnosis (PGD), is a newly emerging technology that has brought with it much controversy. PGD involves the in vitro fertilization of an embryo. The embryos are allowed to develop to a 6 to 10 cell stage, at which point one of the embryonic cells is removed from each embryo and the cellular DNA is analyzed for chromosomal abnormalities or genetic mutations (Botkin, 1998). In doing this, it can be determined which embryos will be most likely to implant and germinate successfully in the…

Discussion on the Negative Implications of the Information Derived from the Human Genome Project

Should man govern nature? This is a question that has been posed more often recently than ever. Human will soon know the secret to life and be able to use that secret in many different ways. This is all made possible by a nation-wide research effort called the Human Genome Project. The HGP is a scientific study and mapping of the estimated 50,000-100,000 genes in the human body. It is being hailed as one of the most important projects in the world by scientists and scholars alike. The information that…

Human Genome Project

It all started back in 1953 with two men by the names of James D. Watson and Francis Crick when they discovered the double-helical structure of DNA. Little did they know they were opening the door to the creation of a perfect world. In 1986, the Human Genome Project, led up by the National Institution of Health(NIH), took a giant leap through this door. They began the long process of mapping out the entire genetic makeup of the human body. The main purpose of the HGP was originally for the…

The Pros and Cons of Genetic Engineering

Genetic engineering is the growing science of the world and is increasingly under the spotlight over ethical issues. Is biotechnology going to save lives, rather than destroy them? and will the benefits outweigh the risks? The main problem with such questions is that we don’t know the answer until we try them out. Like all sciences it is hard to predict outcomes, so far there have been more failures being told than success stories. Genetic engineering is the splitting of DNA out of an organisms gene, and then transplanted and…

Cloning For Survival

It all started back in the fifties when James Watson and Francis Crick discovered the structure of DNA (DSouza NA). Ever since there has been talk of human and animal cloning. It all seemed out of reach and basically impossible, but in 1997 that all changed when a sheep, named Dolly, was the first ever mammal to be cloned. She was cloned for the purpose of curing disease and research on animal organs for human transplantation (Schaeffer 3). Now that scientists know that it is possible to clone literally anything…

The World Of Science, Genetic Engineering

The world of science has experienced many profound breakthroughs and advances in the twentieth century, but none perhaps as great as that of genetic engineering. However, the twentieth century society is not prepared or even willing at times to accept the moral and ethical controversies genetic engineering is creating. Genetic engineering, defined as “the use or manipulation of an individuals genetic material in order to produce desired characteristics or results in the same individual, other individuals of the same species, or other species,” is undoubtedly changing societys relationship with nature,…

Genetic Engineering Offers The Hope Of Cures For Many Inherited Diseases

Genetic engineering, altering the inherited characteristics of an organism in a predetermined way, by introducing into it a piece of the genetic material of another organism. Genetic engineering offers the hope of cures for many inherited diseases, once the problem of low efficiencies of effective transfer of genetic material is overcome. Another development has been the refinement of the technique called cloning, which produces large numbers of genetically identical individuals by transplanting whole cell nuclei. With other techniques scientists can isolate ections of DNA representing single genes, determine their nucleotide…

My topic is “hereditary”

My topic is “hereditary.” I have always been interested in genetics, and this is a large branch of genetics. In this report I also plan to speak about evolution. I would like to learn more about what causes specific traits and what the future might bring. Body: A person gets his or her traits from their parents. These traits include everything from the person’s sex to their mental abilities or problems. These traits are hereditary because they are passed on through genes. They get these genes from their parents and…

DNA: The Thread of Life

The “thread of life”, is deoxyribonucleic acid, otherwise known as DNA. It is the spiral shaped molecule found in the nucleus of cells. Scientists have known since 1952 that DNA is the basic substance of heredity. This was hypothesized, and later confirmed by James D. Watson and Francis Crick. They also know that it acts like a biological computer program over 3 billion bits long that “spells” out instructions for making the basic building blocks of life. DNA carries the bodies genetic code, controls the development of an embryo, is…

Cluster Intersections: Bay Area Bioinformatics

The recent establishment California-based bioinformatics industry clusters is a logical consequence of the intersection of existing local Biotechnology, Information Technology and Venture Capital clusters. The very definition of Bioinformatics: “the science of managing and analyzing biological data using advanced computing techniques, 1” helps to illustrate the nature of this intersection. Research and development for Biotech companies generates volumes of biological data and IT companies provide tools that assist in processing this data. It seems only natural that in light of this mutual dependency and given the proximity of existing IT…

Bioengineering, Or Genetic Engineering

Bioengineering, or genetic engineering is an altering of genes in a particular species for a particular outcome. It involves taking genes from their normal location in one organism and either transferring them elsewhere or putting them back into the original organism in different combinations. Most biomolecules exist in low concentrations and as complex, mixed populations which it is not possible to work efficiently. This problem was solved in 1970 using a bug, Escherichia coli, a normally innocuous commensal occupant of the human gut. By inserting a piece of DNA of…

The Cloning Of Adults, Animals Or Humans

For many years, the cloning of adults, animals or humans has been mostly the object of science fiction, something unforeseen by man. However, “The world was shocked in February of 1997 when British scientist, named Ian Wilmot announced that his research team successfully cloned lamb named dolly from an adult sheep at the Roselyn Institute in Scotland”. (1) For what seemed like a dream for many years quickly turned into reality. The newest and possibly the most controversial phenomena in curing human disease, a phenomenon better known as cloning, was…
