Extract of sample "Genetics and hybrid animal technology"

Download file to see previous pages 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 ...Download file to see next pagesRead More

Consumer Adoption of Hybrid Car Technology

...?Consumer Adoption of Hybrid Car Technology Introduction In a world of increasing concern over the consequences of fossil fuel burning, more attention than ever has been devoted to the prospect and promise of alternative energy. This is especially true with respect to hybrid vehicles. With respect to this vehicular innovation, it is in the interest of authorities to evaluate in technical terms the true utility of the technology. Are hybrid vehicles ultimately efficient in the long run? Can they deliver on the promise of efficient transportation with reduced emissions? This section will investigate vehicle registration data and predictions of consumer demand based upon the Thatchenkery analysis (2008) unless otherwise noted, factual...

Genetics

...?A. The simpli of the DNA’s structure had stumped biologists and no one could accept the fact that a structure so simple can actually store important genetic information and help in transmission of the same. All the genetic information of a cell is stored in the molecules of the DNA present in the chromatin. The molecular structure of the DNA is responsible for its ability to store information (Campbell and Reece, 2009, p86).DNA is double stranded and is twisted to form a helical structure. The strands are made up of nucleotides. Each nucleotide is comprised of 3 parts; a 5-carbon sugar (deoxyribose), a nitrogen base and a phosphate group. The phosphate groups form a phosphodiester bond between the 3rd and 5th adjacent sugar carbons...

... to that of cows and pigs however there are some differences, hence further illustrating the reason why genetic engineering was a better option. Insulin gene is obtained from the double strand that is located on the 11th chromosome. To be more specific, recombinant DNA is cut off from the genomic DNA and these are then purified and prepared for insertion. The cutting of the DNA section is carried out by enzymes which are known as restriction enzymes (Recombinant DNA Technology in the Synthesis of Human Insulin, n.d). This genetic sequence is then inserted into a vector which is referred to as a plasmid. A plasmid is a circular variant of DNA. In order to create a place for the gene to be placed, enzymes are required to cut this vector...

...? Genetics The of our were asked to go to lab and measure height using height scale during practical 10. The whole group of student consisted of male and female students. The heights measured then were arranged into their respective groups. The two groups as mentioned afore were male and female. Since the heights were measured without selecting a particular group of student the sample can be considered as convenient sample. The population from which the sample was drawn consisted of college students. Moreover, the data recorded the heights for year 2013-2014 class. The number of male students was 175 while that of female was 244. The data gathered in the initial stage was in the raw form then it was copied to excel in two columns, one...

Hybrid Cars Technology

..., 2003). This leads to greater interest in energy-efficient technologies, as technology still is the most important source for energy saving. The reshaping of existing patterns of energy consumption strongly affects the transportation sector, which accounts for 21.8% of total primary energy consumption worldwide in 2000, and will account for ca. 34% in 2050 (OECD countries: 28.1% and 40%, respectively) (IEA and OECD, 2003). Road transport is the second-largest sector of energy consumption, right after energy needed for HVAC (heating, ventilation, air conditioning). Hybrid cars are an energy-efficient technology, however, the introduction of more efficient products is often accompanied by rebound effects, which counteract the positive...

Hybrid Technology in Nuclear Medicine

...Hybrid Technology in Nuclear Medicine Essay Introduction Medical imaging is the mainstay of clinical medicine. It is now unquestionable that in the management of all diseases accurate investigation and diagnosis play the role of cornerstones. In certain specialties, physical imaging techniques play central role, not only in diagnosis but also in planning and monitoring of the treatment. The diagnostic medical imaging began with ionizing x-radiation. It is still widely used as the conventional method of radiologic imaging. With the advent of new technologies and better understanding of the physics of imaging technologies, there had been new methods of diagnosis that manipulated cellular metabolism and nuclear components of the cells...

Emerging hybrid technology in the automotive market

...Topic: Emerging hybrid technology in the automotive market Introduction: Hybrid means something with two different types of components performing thesame task. In case of Hybrid technology in automobiles, a device that is normally used for propulsion is accompanied by another device using another source of energy and transport method. These two energy sources of hybrid vehicles are composed of primary and secondary sources. The primary energy source is the original one or the conventional one and is refilled manually e.g. with CNG or petrol. The secondary energy source, however, is emptied and refilled automatically by the vehicle itself. Secondary energy most often originates from primary source or sometimes comes from an external system...

Genetics

Genetics tasks True-breeding organism is an organism that always passes to offspring a certain phenotypic trait. According to the Mendel`s laws true-breeding organism is an organism which shows a homozygote phenotype (Stansfield). All individuals who have short wings is recessive homozygotes with ww genotype; therefore, such flies with short wings are true-breeding ones. In order to find in mixture of fruit flies a true-breeding individual with normal wings it is necessary to conduct test cross analysis. To carry out this analysis flies with normal wings should be crossed with that who have short wings. Thus, obtained offspring that do not show segregation of wings size trait are heterozygotes (Ww), and therefore their parents a...

GENETICS

Biotechnology Biotechnology is defined as an industrial study of science. It is one of the fields that integrate knowledge presented by different sciences to upgrade the lives of living things. Coulter, Meyers and Varacalli (2012, p.32) regard “Biotechnology as the application of the scientific and engineering principles to the processing of materials by biological agents to provide goods and materials.” From this assertion, one can deduce that the primary role of biotechnology is to upgrade the life and to increase productivity. Achievement of these roles, however, is enhanced by the change of the genetic codes of the DNA through the assistance of science. In connection with this, it is evident that biotechnology has led to the i...
