According to Neglia (2011), paleontologists estimate that 90 percent of flora and fauna that ever existed have gone extinct. Biotechnology scientists have embarked on extensive use of biotechnology to breed and conserve the endangered species. Biotechnology constitutes techniques that use substances from living organisms to make modified products or develop microorganisms for specific purposes (Gonzalez-Benito & Martin, 2011). Most of the biotechnologies have already been adopted while others are being developed. These biotechnologies include embryo-transfer, artificial insemination, multiple ovulation, ova-pick-up, In-vitro fertilization, embryo splitting, sperm sexing and cloning. Embryo-transfer Embryo transfer is a step in the process of assisted reproduction where embryos are placed in the uterus of a female with the intention of establishing pregnancy (Thongphakdee et al, 2011). Biotechnologists have identified this procedure to be one of the best technologies in protecting species extinction. The primary demerit of embryo transfer is that it is not economically feasible in small-scale application; however, embryo transfer greatly contributes to genetic improvement in local breeds and restoration of endangered species (Klotzko, 2006). Embryo transfer is advantageous since it affords the possibility of producing a variety of progeny from a female species. This means that one female can be enhanced through biotechnology to produce several offsprings, just as male sperms can be used to fertilize several ova in Artificial Insemination. Biotechnologists, for example, have succeeded in increasing the lifetime productivity of Brown Pelican, Cheetah, Desert Tortoise, and Cockatoo from between six and ten offs springs to twenty-five (Iguchi & Kitano, 2008). Increased numbers of calves ensure that these species are not endangered and protect them from extinction (Hosseini, Fazilati, Moulavi, Foruzanfar, Hajian, Abedi, Nasiri, Kaveh, Shahverdi, Hemami & Nasr-esfahani, 2009). Another advantage of embryo transfer is that genetically outstanding animals have the potential for breeding program and their male young ones are usually selected for use in Artificial Insemination (Field, 2012). These male offsprings have excellent adaptive features that enable them to withstand harsh conditions in diverse environments, thus protecting endangered animals from possible extinction. Scientists can enhance the rate of genetic change with specially designed breeding schemes. This increases the chances of maximizing on the advantages of increased intensity of female selections and possible increase in turnover of generations (Verma, Kumar, Kumar & Chand, 2012). Increased generations turnover is the objective of genetic biotechnologists in their struggle to achieve protection of endangered species from possible extinction. Ethical considerations concerning embryo transfer include consent of donors and recipients, avoidance to mix gametes or embryos from different sources, and meeting the settlement of donor expenses. Artificial Insemination Artificial insemination involves deliberate introduction of semen into a female oviduct for the purpose of fertilization by means other than copulation (Araujo, Ginther, Ferreira, Palha?o, Beg & Wiltbank, 2009). The male ...Download file to see next pagesRead More

...IDENTIFICATION AND DETERMINATION OF ABSORPTION SPECTRA OF CHLOROPHYLL Photosynthesis is a regulated and a multi-step process. It is the process by which the plants produce energy from the sunlight to produce sugar which in turn is used for cellular respiration to produce ATP, the store of energy of the cells. This conversion of the less used energy into a usable chemical energy is assisted by the green pigment called chlorophyll. The photosynthesis uses the water molecule and releases oxygen molecule. (Tanaka and Makino 2009). The pigment is a substance that absorbs light and the color is produced due to the reflection of the light that is not absorbed. Chlorophyll absorbs all wavelengths of the visible light except the green... AND...

.... Recent technological advancements in the application of biotechnology have raised certain ethical concerns among people. Genetically engineered food has been a subject of hot debate for the past three decades. Genetically engineered food is an application of biotechnology in agriculture which has enabled us to design and create plants with the desired characteristics through genetic engineering. This idea has been rejected by some and praised by others. Both parties do realize how this technology could revolutionize the world but the idea of this revolution differs. The proponents and opponents of...

A search is carried out for chemical and biological substances targeting biological markers and likely to have drug-like effects. Out of the many new compounds identified during the discovery process, a few are clinically evaluated and considered safe for testing in humans. Further clinical testing is done and effective compounds are approved for treatment. There are many new scientific approaches being used to identify targets and obtain lead compounds. They include the use of...

...Rhetorical Strategies Used in the Film Gattaca The three rhetorical strategies that Andrew Niccol used in the film Gattacawere logos, ethos and pathos. Logos One of the rhetorical strategies used by Andrew Niccol for the audience to be sympathetic to Vincent is logos which is the use of logic or reason in conveying an idea. The rhetorical strategy logos was obviously used in the film to draw sympathy for Vincent when society put so much emphasis in predetermining the destiny of individual just by his or her genetic make-up. Gattaca’s over reliance on logic puts the audience off because it failed to consider other factors such as persistence, will and discipline that would make an individual effective and successful. ...

...(Genetic Science Learning Center, 2013). Dolly the Sheep was conceived and born into the world; however she suffered from a few health conditions, including rapid aging, which ultimately claimed her life at half the life span of a normal sheep. This means that cloning does come with the some obvious and unavoidable side effects that cannot go unaddressed. At the same time, it, also, offers some amazing potential benefits that cannot be ignored. For this reason, the debate over cloning of any living thing will remain ever-present for some time to come. Cloning is at the top of the list of potential biotechnological advances. Given the provided definition of biotechnologies, cloning,...
