Agriculture is at the heart of the progression of the human race as a distinct species, and our success can be measured directly to our advancements in terms of crop improvement. Agricultural biotechnology has been used to generate plants with novel traits, such as resistance to biotic and abiotic stresses, as well as pests. Plant biotechnology as a discipline entails both molecular plant breeding and the development of transgenic plants. Molecular plant breeding can be accomplished by selecting plants with desirable characteristics using complex molecular techniques such as marker assisted selection. Transgenic plants can be generated either via Agrobacterium-mediated Continue reading...

Firstly, the synthesis of β-galactosidase constitutes the induction of SOS response by genetic toxins, and the level of alkaline phosphatase activity indicates a range of cytotoxicity. From the experiment, the β-galactosidase and phosphatase activities of E.Coli PQ37 exposed to nanoparticles Au NPs and other nanoparticles showed minimal changes. As such, Au NPs and the other nanoparticles used in the experiment were not genotoxic. However, it was noted that cytotoxicity for Au and Ag ions there was reduced alkaline phosphatase activity in parallel with β-galactosidase. This is an indicator that the ions are not genotoxic. There is need conduct tests Continue reading...

Based on: UN/WHO, 20 Questions On Genetically Modified (Gm) Foods, http://www.who.int/foodsafety/publications/biotech/20questions/en/

How does WHO define genetically modified organisms? List any lingering questions or concerns about this definition.

Genetically modified organisms are those organisms whose genetic material has been artificially altered. This kind of change cannot occur naturally through mating nor through natural recombination but has been introduced into the organism through modern technology, sometimes called "recombinant DNA technology" or "genetic engineering". Concerns regarding this practice include the question whether this process is leading to the creation of new species and whether there are truly any real benefits from GMOs because they are generally not significantly cheaper, does not have increased shelf-life, nor better taste — concerns Continue reading...

The Human Genome Project (HGP) was a scientific research project whose goal was to map the gene sequence of human beings. HGP was initiated and sponsored by the U.S government, but involved institutions and scientists from different regions of the world such as Japan, China, Germany, the U.K and France, making it the largest collaborative scientific research project of its kind. The project mapped about three billion base pairs (estimated to nbe between fifty and a hundred thousand genes). It started in 1990 after four years of development and planning and ended thirteen years later in 2003. Interestingly, the Continue reading...

Introduction

Alzheimer`s Disease is a chronic neurodegenerative disorder that is currently affecting an estimated 25 million people across the globe (Burock et al, 2014). The number of infection is expected to increase to approximately 75 million in the next 30 years. The disease is mostly experienced by elderly women in the age limit 65-85 (Solomon et al, 2014). However, in extreme ages such as 85+ years, the condition presents itself in pronounce levels. The prevalence of the disease is observed in both developed and underdeveloped nations. The disease is characterized by prominent psychiatric symptoms, memory impairment, and behavioral disturbances. Continue reading...

The article begins with defining what exactly designer babies are. It says that the designer babies are those whose genetic makeup is decided by adding or deleting genes which represent a particular character. These babies are created by IVF, the embryo is then made to undergo genetic engineering which results in the desired modifications. After the alterations are made, the resultant embryo is placed in the womb (Agar, 2006). This method is currently used in plants to make them resistant again certain pesticides and pesticides. But doing the same in the human beings is not as easy as it Continue reading...

GMOs are one of the most controversial topics of the last years. Genetically modified organism (GMO) is an artificially altered organism using genetic engineering techniques. This definition can be applied to plants, animals and microorganisms. Genetic changes are usually made either in scientific or economic purposes. Genetic modification differs by purposeful changes in the genotype of an organism as opposed to the random characteristic of natural and artificial mutation process. The main type of genetic modification is the employment of transgenes for generating transgenic organisms. In agriculture and the food industry the GMOs are referred only to organisms modified Continue reading...

Introduction

Niemann-Pick Disease represents a group of inherited, genetic disorders, clinically referred to as leukodystrophies, which are more commonly known as lipid storage disorders. In each of the variations of the conditions all share one specific aspect in common, they cause lipids to not be properly metabolizes and inappropriately allows lipids, fats, to accumulate in different organs of the body, including the liver and brain. Over time this accumulations become severe enough that permanent damaged is caused (Kugler, 2014). This condition, due to its genetic origins, is inherited and is often a cause of serious health problems in new infants, Continue reading...

Abstract

Clostridium is a gram-positive bacillus bacterium. Any disturbance to healthy microbes of GI tract due to antibiotics activates the cytotoxins release by Clostridium, resulting in adverse effects. The toxins released by Clostridium are known as botulinum toxin. Its toxins are potent poisons but have several therapeutic qualities. It can block neuromuscular transmission, and this ability transformed it into a therapeutic tool. Botulinum toxin blocks acetylcholine release at the neuromuscular junction as well as in the sympathetic and parasympathetic neurons. It is used in vaccines to weaken overactive Continue reading...

Cancer is a terminal condition characterized by abnormal cell growth in the body. It is mostly associated with tumors that often put the patient at risk of spreading to other body parts. Scientific studies have not been conclusively clear on the causes of cancer. There have been several hypotheses about factors that have contributed to this disease. Most studies show that smoking is a major factor that contributes to abnormal cell growth. Obesity, lack of physical exercise, exposure to radiation and some infections such as hepatitis are also part of the factors attributed to cause cancer in humans. There Continue reading...
