Genetics and hybrid animal technology - Essay Example Genetic and hybrid animal technology describes a group of techniques that are applied to modify or manipulate the genetic make-up of organisms using recombinant DNA. According to Montaldo (2006), the technique allows for identification, replication, modification and the transfer of cells or tissues and, in some cases the complete organism. On a wider perspective, the technology, which entails the incorporation of DNA markers for selection, aims at improving the quality of breeding and the subsequent offspring. The technology relies on genetic information of animals in order to effect the improvement. Animal selection is usually done by understanding the effect the genes to be transferred will have the same. According to Montaldo (2006), the transfer of a particular gene depends on the expected advantages it is likely to proffer to the animal. The following techniques are used in genetic and hybrid animal technology. Transgenics: This is the most common technique applied in hybrid animal technology. Also referred to as recombinant DNA, the technique involves the transfer of a particular trait from one organism to the other (Bioscience, 2015). In transgenic, the gene splicing method facilitates the introduction of a gene for a required trait from one organism to the other. Upon the successful transfer, new DNA is integrated into the second animal’s genetic material, and this leads to the creation of a transgenic animal (Montaldo, 2006). The transgenic animal acquires new characteristics following the alteration of its protein makeup. Cloning: In this technique, nucleus of differentiated adult cells is moved to an oocyte without of nucleus (Bioscience, 2015). The result is the production of several copies of almost the same animals (Bioscience, 2015). According to Bioscience (2015), this technique is used in producing copies of animals with superior traits such as high milk production and wool

The Radiation Exposure in Hiroshima Research Paper

The Radiation Exposure in Hiroshima - Research Paper Example The intermediate stage lies between 10 and 12 weeks after the initial exposure to the radiation. The deaths in Hiroshima and Nagasaki stemmed from ionizing radiation. In Hiroshima alone, about 140,000 died instantly and 100,000 were seriously injured. Syndromes. That the damage that had been left by the nuclear radiation was extensive, is a matter that is underscored by the trail of medical or health complications it left in its wake. Some of the symptoms that Japan had to deal with include bleeding, hair loss, nausea, flash burns, blood cancer and a higher level of vulnerability to leukemia, malignant tumors, and cataracts. Some of the syndromes that accompanied the radiation included small brain size, skin, organ and blood cancer, lower Intelligence Quotient, mental retardation, cleft and lip palate, blindness, delayed development and Spinal Bifida. Other conditions that accompanied the radiation include. The fact that the radiation had claimed Hiroshima and Nagasaki’s 90 pe rcent of medical personnel and left many others disabled did not make things lighter. The same state of affairs also dilapidated medical supplies and resultantly, claimed more deaths. burns- Long-term impact on the exposed population * Cancers, genetic defects, other biologic effectsIn addition:- Define any radiation units used in your research paper (R, rem, rad, Ci, Sv, Gy, Bq, etc.)- Define the term LD 50/30- Describe the LD 50/30 in humans- Current standards for Effective Dose Equivalent limits for occupational and non-occupational exposures
