Lareina Chen Mr. Hayward 9A January 11th, 2017 Genetic Engineering Essay Genetic engineering is a powerful and dangerous technology. Sometimes called genetic modification, genetic engineering is the process of altering the DNA in an organism’s genome. Editing the sequence of nucleotides can sometimes lead to extreme harmful effects on the human race, while on the other hand generates huge benefits for society. While talking about Genetic engineering, it is carried out by CRISPR. CRISPR stands for “clustered regularly interspaced short palindromic repeats.” It can quickly twist most of the genes in any plant or animal.
To increase the size of DNA fragments used in transgenesis, scientists are cloning them in yeast or bacterial artificial chromosomes (YACs and BACs). This has increased the use of transgenic mice as disease model. Single Gene Knock-Outs and Knock-Ins These are models to target a mutation to a specific gene locus and are particularly useful if a single gene is shown to be the primary cause of a disease. Knock-out mice carry a gene that has been inactivated while knock-out mice are produced by inserting a transgene at the exact location where it is overexpressed. Many knock-out and knock-in mice have similar, if not identical phenotype to human patients and are therefore good models for human
Natural transformations in which the uptake, integration and expression of extracellular DNA occurs under natural populations of bacteria. Through this mechanism bacteria can acquire DNA from foreign species which are not accessible to mobile genetic elements or bacteriophages. The requirement for this process is that, the bacteria should first develop a physiological state of competence. Some bacterial species, such as Neisseria gonorrhoeae and Haemophilus influenzae, are competent to accept DNA, whereas some others, such as Bacillus subtilis and Streptococcus pneumoniae, become competent after reaching a certain physiological stage in their life cycle (22,15). 2.
Genetic engineering is manually changing the genetic structure of cells by adding a new DNA which has one or more new traits that aren’t existent in the particular organism. The aim of the genetic engineering would be to improve organisms. An example of a genetically engineered organism would be plants that can handle herbicides or crops with higher or lower oil content. Genetic engineering works by removing a gene from an organism and inserting it into another organism, making it capable to express the trait given from the gene. One specific gene is located and copied from thousands of genes, this is called gene cloning.
The bacteria also plays a huge part in this process too, it’s not just the antibiotics. Bacteria is a microscopic prokaryotic organism(s), bacteria can adapt to most medicines and conditions rather quickly, but Penicillin was different, it was like fighting bacteria with bacteria. 2 million years ago bacteria were the only form of life on earth, now that we’re here they need a place to live, which is in our bodies and other various
Human eugenics has become a popular technology in the biology world of reproduction. The idea of conserving the superior traits and deleting the tainted traits has become an exciting movement where even novels like Brave New World has predicted us with the dramatic future of eugenics. Although the idea of deleting tainted traits such as disease seem ideal, the fear of creating “perfect” traits will create dominance from the upper class and will strip individualism. John H. Evan talks about the pros and cons of human eugenics in his article. Inspired by the novel Brave New World, Evans first introduces the idea of class separation between the selected designed babies.
Is Genetic engineering Safe? Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not. This essay will look more on the advantages and disadvantages of genetic engineering.
I believe that evolution is the true explanation of how we came to, I believe that we all came from common, shared ancestors. Octopi have been seen in observation to change how they use their RNA to code for proteins. The octopi change their RNA, in order to have different proteins produced, however it could be beneficial to them. While this is not any large scale change, it proves that there are possibilities of change within animals, which can lead to large scale differentiation
Since techniques have become more precise and readily available, it opens the possibility of creating new species and completely altering a species. But with that come environmental and health concerns? By creating a new organism and releasing it into the wild, could another species be entirely eradicated? Does human consumption of genetically modified organisms affect humans in any way? All these questions are valid and should be highly researched with each new genetically modified organism, however, the benefit of genetic engineering out weight the
Genetic engineering is one of the most controversial issues in the society. People say that it will improve people’s lives and to me is very true and some people say that it will be a threat to life on earth which is also true. To expand this thought, here is what I have to say. Apiece of human cell holds an enormous storeroom of genetic information in a quantity of genes. The techniques of genetic engineering let scientists to discover specific genes, to eradicate any one of those genes from an organism’s chromosome, to duplicate or make a big number of matching copies of that gene, to scrutinize a replica in detail, to transform it, and to reinsert it into the genetic bits and pieces of the being from which it was consequent or into the
