Analysis of theoretical explanations of the relationship between technology and society - Essay Example 2.1 Technological determinism is a reductionist theory which holds the assumption that a society’s technology plays a crucial role in driving the development of its social structure as well as the cultural values (McLoughlin 1999, 32). The social structures evolve as a result of adapting to the technological change. The theory also suggests that technology moves on its own course which is normally independent of the human direction. It is therefore regarded to as an autonomous system which ultimately permeates all other sub systems of a society. Technological determinism contributes to the conclusion that emergence of automated technology inevitably raises the level of skill as well as the autonomy of the work force. According to Webster (2002, 34), technological determinism is also a clear explanation of the relationship between technology and society which asserts that technology plays an important role in determining the social existence within a society. In most instances technological changes act as catalysts for societal change. The changes are either seen as literally outside the context of the society or metaphorically outside the society. In addition, the technological developments take place as a result of natural logic which is not socially or culturally determined. As a result, the developments enact change and social adaptation (McLouglin 1999, 39). 2.3 The reason as to why I think they are perfect examples is due to the impact they have on the society and their autonomy nature. Bearing in mind that technological determinism refers to technology as an autonomous system, the quotes support the idea behind that. For example, robots are slowly being assimilated into the systems of our homes and lives whereby they will play a central role later in the century just like both the internet and combustion do now. In reference to technological determinism, the revolution of

The Science of Nutrition - Essay Example Describe the processes involved in cellular protein synthesis. How would synthesis be affected by intake of an otherwise adequate diet that is very low in glycine or low in tryptophan How would synthesis be affected by a diet that is low in energy Proteins are widely used in cells to provide different functions such as providing structural support for cells or to act as enzymes to catalyze certain reactions. Since the beginning of evolution, cells have developed the ability to synthesize proteins. To manufacture proteins, cells follow a very systematic procedure that first transcribes DNA into mRNA and then translates the mRNA into chains of amino acids. The amino acid chain then folds into specific proteins. [11] These two processes are 1. DNA Transcription Protein synthesis initiates in the cell's nucleus when the gene encoding a protein is copied into RNA. Genes, in the form of DNA, are rooted in the cell's chromosomes. The process of transferring the gene's DNA into RNA is called transcription. Transcription helps to increase the amount of DNA by creating many copies of RNA that can act as the template for protein synthesis. The RNA copy of the gene is called the mRNA. After transcription, the mRNA is transported out of the cell's nucleus through nuclear pores to go to the site of translation, the rough endoplasmic reticulum. [4] 2. RNA Translation After the mRNA has been taken to the rough endoplasmic reticulum, it is fed into the ribosomal translation machineries. Ribosomes begin to read the mRNA sequence to convert the mRNA into protein. The mRNA sequence is matched three nucleotides at a time to a complementary set of three nucleotides in the anticodon region of the corresponding tRNA molecule.... As the essay declares proteins are widely used in cells to provide different functions such as providing structural support for cells or to act as enzymes to catalyze certain reactions. Since the beginning of evolution, cells have developed the ability to synthesize proteins. To manufacture proteins, cells follow a very systematic procedure that first transcribes DNA into mRNA and then translates the mRNA into chains of amino acids. The amino acid chain then folds into specific proteins. According to the report findings protein synthesis initiates in the cell's nucleus when the gene encoding a protein is copied into RNA. Genes, in the form of DNA, are rooted in the cell's chromosomes. The process of transferring the gene's DNA into RNA is called transcription. Transcription helps to increase the amount of DNA by creating many copies of RNA that can act as the template for protein synthesis. The RNA copy of the gene is called the mRNA. After transcription, the mRNA is transported out of the cell's nucleus through nuclear pores to go to the site of translation, the rough endoplasmic reticulum.

The mRNA sequence is matched three nucleotides at a time to a complementary set of three nucleotides in the anticodon region of the corresponding tRNA molecule.
