CRISPR is a new technology‚ a method that can edit genomes. It makes it possible for scientists to manipulate and make changes to the DNA in the cells of all organisms. Since this is such a new discovery‚ there hasn’t been done much testing and experimenting‚ which makes it unknown and none predictable for humans. It is said that with CRISPR‚ scientists will for example‚ be able to change genes in human embryos‚ and create so called “designer-babies”. There has been a lot of discussion around this

In chapter 5‚ I learned that an adult human contains ten times as many foreign microbial cells as mammalian cells. I also learned a lot about host manipulation in animals from spiders to humans. I found it really intriguing that the cold virus actually triggers your sneezing reflex so that it can infect others around you. Other viruses‚ such as cholera and some STDs‚ also use various degrees of host manipulation to find transmission channels. I also found it interesting that our sense of disgust

biological processes have come about is of a great importance to scienticists. In terms of exploring the concept of biological phenomena‚ scientists have specifically relied on model organisms to obtain the answers they require. Model organisms are non-human species that are studied in great detail to provide useful knowledge on biological phenomena‚ which can further be more generalised to more complex organisms that are difficult to study directly (Encyclopedia of Life‚ 2017). One of the most widely

After the completion of the Human Genome Project‚ scope for genetic engineering was greatly expanded. Every part of human DNA was mapped and recorded for its role in the DNA. This also made changes in DNA possible‚ allowing scientists to remove or fix any mutations that could lead to harmful consequences. Due to the success of the project it is possible that in a few years couples may even be able to design their children by picking not only their children’s physical appearance but also their children’s

On the other hand‚ in the 1960s the medication was based on the vaccinations but in the 2000s the Human Genome project finished and the technology and science had changed a lot. At the beginning of the 2000s‚ with the use of internet‚ e-mails and cell phones were the base of the communication‚ unlike the letters and dial-up phones that were used in the

organism may be tiny in size‚ but their impact on human evolution is tremendous! Carol MacKintosh‚ a professor in the College of Life Sciences at the University of Dundee‚ defines them as “…a very distant cousin to humans and other vertibrates. It is the creature most similar to the original spineless organism that existed before a major genomic event occurred.” A new study indicates a genetic error‚ which took place 500 million years ago‚ led to human evolution. This organism went through two doublings

cells‚ the researchers relied on the gene editing system known as CRISPR to grab the free-floating pixel codes and insert them into the bacteria’s genome. CRISPR is a group of proteins and DNA that act as an immune system in some bacteria‚.When a virus infects a bacterium‚ CRISPR cuts out part of the foreign DNA and stores it in the bacteria’s own genome. The bacterium then uses the stored DNA to recognize the virus and defend against future attacks."The sequential nature of CRISPR makes it an appealing

widely known as humans ’ close relatives from the sea or so the “other humans” who chose to live in the sea. They have human characteristics that most animals do not have. They are amazingly intelligent‚ friendly‚ and genetically similar. A research done by John Lilly concludes that dolphins are in fact intelligent as humans. Many other scientists have studied dolphin behaviors years ago and now have come to a possible result of dolphins being the closest relatives to humans. Their brains are

“Frankenstein and Human Cloning” What is life? What defines a person? Do you believe humans should have the right to create life? Are there any consequences? In 1831 Mary Shelly wrote Frankenstein or; The Modern Prometheus‚ a magnificent depiction of a man taking up God’s role of creator of life. Victor wanted to achieve biological immortality. Yet‚ within the instance of success Victor outright rejected his creation as “monstrous”‚ a unit for being unworthy of human life. In this paper‚

History of DNA Technology During the early1960s‚ there was great progress being made in beginning to understand the structure of genes and the mechanisms of their replication‚ expression‚ and regulation in prokaryotes and the viruses that began to infect them (Berg 2010). However at the time it was still unknown as to whether or not these findings applied to eukaryotes. This is because the tools used at the time for exploring genetic properties were not fit for the task. By the spring of 1972‚ the
