Essay On Transgenic Animals

770 Words4 Pages

Transgenic animals are animals that have gone through a series of steps that produced a newly modified genome. Understanding how transgenic animals are made and what are their importance can make revolutionary changes in modern medicine, they can provide alternatives in terms of treating diseases and even preventing them. Therefore, this project is dedicated to the benefits of transgenic animals and the interventions they provide in our health as human beings.
In definition, transgenic animals are animals that have been genetically modified by adding genes from another organism into their genome, and that produces a genetically different organism that has the characteristics of both organisms. The fields in which this process can be helpful …show more content…

Another known method for creating transgenic animals is Retrovirus-Mediated Gene Transfer. It may sound a bit complicated but it’s not, it involves using a retrovirus as a vector (a cell that can be implanted in a host, it contains genetic material for cloning purposes) that gets implanted in an organism and the bred for at least 20 generations to produce the transgenic organism with the desired genes. A retrovirus is simply a virus that contains its genetic material in the form of RNA instead of DNA. This method is time consuming because of how many generations need to be produced in order to get the desired organism. The last method that is commonly known to produce transgenic animals is Embryonic Stem Cell-Mediated Gene Transfer. It involved using stem cells from different embryos and then inject it with the desired genes, after that it gets implanted in an embryo of a host. This method allows us to test for the transgene in a cellular stage, whereas in the other two methods we would require a live offspring to do so. (Margawati,

    In both of these excerpts they talk of genetic engineering, but with what one is the right way to go about it? Both sides have numerous good points and arguments. Genetic engineering is a method that scientists use to clone things such as sheep back in the day. Today genetic engineering can help with diseases such as parkinson's. So the debate is to decide whether it is a good thing to take embryos or making them in a petri dish.

    Methods of genetic engineering in our world differ tremendously from methods used in the novel. In Brave New World, DNA manipulation is a perfectly accepted process used to create individuals who will later be predestined to varying social classes. Bokanovsky’s Process is a method of genetic engineering in Brave New World that can create hundreds of embryos from one singular egg. The Podsnap Technique involves increasing the speed of maturation of eggs, so one ovary may produce more eggs that are fertilized at the same time. These differ greatly from techniques used in our society: somatic, cloning, and germline methods.

    147 Words  | 1 Pages

    Therapeutic cloning, also interchangeable with somatic cell nuclear transfer (SCNT), is a procedure that helps cure ailments in science. To begin the process, the haploid nucleus, that contains the genetic makeup, is separated from the fertilized egg. Somatic cells are then obtained from embryonic tissue and injected into the fertilized egg. If done so correctly, a cleavage is formed and cells divide due to mitotic division. In result, this forms a blastocyst where new stem cells are cultivated for further growth.

    Human genetic modification is the manipulation of genes in human DNA so that defective genes don’t obstruct proper functioning, and so that inherited diseases are not passed on. Those against it may argue that genetic modification is simply unnecessary, immoral, or interferes with nature’s course. However, genetic modification overall is and will continue to be beneficial to the mental and physical health of the entire human species. Falling under the umbrella of biology, it is sensible to consider the studying of genes as a significant aspect of the biological sciences because it’s learning how to manipulate them in order to progress preventative medicine and create the possibility of a healthier future. One method of genetic modification

  • The Pros And Cons Of Artificial Selection

    Humans have been successful with manipulating genetic transfer for thousands of years since our nomadic hunter gatherer ancestors settled and started farming animals and cultivating plant crops. Humans used the same principle of natural selection (selection by the environment of the ‘most fitted’) to develop artificial selection (selection by humans of the ‘most fitted’). Artificial selection, also known as ‘selective breeding’ is a procedure that is still carried out in today’s world that which organisms with desirable traits were bred together. It was the earliest form of genetic manipulation. Over the last few decades, along with the advancement of technology, humans have developed sophisticated methods to manipulate genetic information

    Therapeutic cloning is where cells are taken from a host subject, more than often it is a human, and use them to create or to treat the person. This type of cloning stemmed from stem cell research when scientist had figured out cells can be used to produces and repair organs. Than in the medical field it is referred to as somatic cell nuclear transfer of SCNT for short (Liu par. 2).
