I Help build the future of Wikipedia and its sister projects! Read a letter from Jimmy Wales and Michael Snow. I [Hide] [Help us with translations! ] I DNA vaccine What is antisense technology? Antisense refers to opposing the normal order (“sense”) of the code in DNA. The DNA (deoxyribonucleic acid) in genes directs cells […]

Developmental Biology is the study of a procedure whereby a single-cell segregates and selectively triggers expression of genes to generate compound organisms made of various cell groups. There are three major forms of substantiation that are acknowledged in all of experimental natural sciences when trying to understand a gene’s purpose (Gilbert, 2006). The first one […]

The virus introduces reverse transcriptase protein into the cell, which transforms RNA into DNA. This generates genetic information that the host cell can utilize to replicate the RNA virus in DNA format. Essentially, a virus consists of a protein capsule enclosing nucleic acid, which can be either DNA or RNA (with DNA being our genetic […]

Genetic Engineering, history and futureAltering the Face of Science Science is a creature that continues to evolve at a much higher rate than the beings that gave it birth. 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 […]

The Perfect World. Imagine a world full of Lebanon James, Adrian Gonzales, Beyond, and Brad Plat, which was developed by the parents that chose to transmit featured genes into their fertilized eggs through IF (in vitro fertilization clinic and these so-called genetic engineers are able to mutate both internal and external physical traits exactly the […]

Sheep and goats were domesticated in the Fertile Crescent around 8,000 BC. Pigs were first domesticated in China around 7,000 BC. Yaks were tamed in Tibet about 5,000 BC, and horses were domesticated in Eastern Europe around 4,000 BC. The rock pigeon was the first domesticated bird found in Greece, Egypt, and Mesopotamia by 3,000 […]

Fecal transplantation, also known as bacteriotherapy, involves transferring stool from a healthy donor to the gastrointestinal tract of an ill recipient. The purpose is to treat C. difficile colitis by restoring bacterial balance in the digestive area after antibiotics have eliminated important bacteria. Fecal transplantation serves as a therapeutic intervention for recurrent C. When encountering […]

Practice Questions for FALL FINAL Biology KEY Note: These are a few sample questions that you can work through for more practice with genetics and experimental design. You should also review the evolution and experimental design quizzes and exams. These questions do NOT cover all of the material covered this semester. Completion of these questions […]

By utilizing our knowledge of the genetic code, transcription, and translation, we can elucidate the mechanism through which a mutation can cause a single gene disorder. In this discussion, we will offer an illustration of such a disorder. This will encompass information concerning the gene that is affected, its influence on the final product generated, […]

Monsanto Case Study Monsanto is a multinational world leader in the production of the herbicide glyphosate and in the manipulation of genetically modified (GM) seeds. They were a chemical company, which shifted into the new life science area developing numerous patents related to genetic techniques and GM seeds variety. The company entered in the agrobiochemical […]

ABSTRACT The microevolution of Alu element TPA-25 was tested in the experiment through the examination, observation, and analysis of population alleles distribution under the Hardy-Weinberg Theory of Genetic Equilibrium. Alu elements affect the genome by causing insertion mutations, recombination between elements, gene conversion, and alterations in gene expression. In the lab PCR was used to […]

Question one: the human genome project. The human genome project is an international scientific research project to sequence and map all of the genes of human beings. completed over thirteen years by the U. S. department of energy and the national institutes of health, however many different countries such as Japan, the U. K. , […]

In 1998 the first genetically modified (GM) food was approved for public consumption. Since then GM foods have become part of the world’s food supply and are produced in several countries. While horror stories in the 90s promised dire consequences for introducing GM foods to the populace most of those problems have failed to arise […]

A genetically modified organism (GYM) is a plant, animal, or microorganism whose genetic code is added, altered, or subtracted to give characteristics the organism does not have normally. Based on the links provided in class and my research, I determined that GYM production can be beneficial to the world’s future. Based on the Youth video […]

Naked Mole Rats possess anatomical, physiological, and behavioral features that are distinct from most mammals. They have incisor teeth for chewing on tough, fibrous plant materials and digging, lack of fur and reduced eyes, and soldiers that defend the colony against predators and rivals instead of fleeing. Unlike most mammals, Naked Mole Rats lack features […]

Just imagine the scene: and newlywed wife and husband are sitting down with a catalog, browsing joyously, pointing and awing at all the different options, fantasizing about all the possibilities that could become of their future. Is this a catalog for new furniture? No. This catalog for all features, phenotype and genotype, for the child […]

In the past decade genetically modified foods have been have made a world of stir about whether these foods are beneficial to our society or if they are actually hurtful. There is plenty information that is available to help support both sides of the issue but for every positive thing there is also a negative […]

In recent years science has been using recombinant DNA to genetically modify animals, plants and now technology has advanced to the point where there is constant speculation on manipulating human DNA. Recombinant DNA, or more commonly known as ‘genetic engineering’ involves “the combination of DNA from one organism with DNA from another organism”. There are […]

The subject of genetic engineering has always been a controversial one, that has divided opinion for years, although in today’s society it is more important than ever. Although the possibilities of genetic manipulation have been theorised as early as the 17th century and H. J. Muller was artificially mutating genes of Drosophila with x-rays in […]

There is much controversy surrounding the topic of genetically modified foods, a subject that provokes an emotional debate as some of the ideas contradict many moral and religious beliefs. Many ‘disadvantages’ are merely the moral views of people, and have little or no scientific link, such as the belief of consuming a plant with a […]

There are two essential substances found inside bacterial cells required before the process can begin. Present in the cytoplasm of a bacterial cell are a number of small circular pieces of DNA known as plasmids. Also present within the bacterial cell are restriction enzymes which cut DNA molecules at specific sites. By selecting the correct […]

Deoxyribonucleic acid or its commonly known name DNA – is a molecule that contains our genes. It forms part of a chromosome and is only found inside the nucleus of a cell. Our DNA consists of units called nucleotides. Each consists of a 5-carbon sugar, deoxiyribose, a phosphate group and a nitrogenous base – adenine […]
