Epstein-Barr virus

Gene Therapy and Genetic Engineering in Human Beings We, as human beings, all start off the same way. A lucky sperm meets an egg and forms the beginning of a whole new life. From that very moment it is predetermined in our DNA that we will have a certain color of hair, be of a certain height, and what color that our eyes will be. Then, approximately nine months later we are welcomed into the world carrying with us every trait that our DNA tells us to have. People will come in to see the miracle…

There are many ways of getting sick such as airborne, touching someone. For a long time this is how people have gotten a cold or chicken pox. As medicine is readily available to aid in the recovery of an illness. Viruses can become resistant to medicine just as our bodies could resist to some sicknesses. In the book Biological Terrorism by Steve Goodwin and Randall W. Phillis they present a history of microorganism used to help cure diseases and misused by Medics, and biological warfare. To…

the origin of the CRISRP acronym. These CRISPR sequences are specific patterns of DNA sequences that are capable of being edited out of genes. Using the CRISPR system, bacteria are able to destroy the genome of invading viruses and thus prevent the virus from being able to replicate and survive in its host.…

Introduction Bacteriophages, informally known as phages, are a specific type of virus that only infect bacteria. Since their discovery in the early 1900s , researchers have began studying the various behaviors and interactions of phages within the environment (Poxleitner, Pope, Jacobs-Sera, Sivanathan, & Hatfull, 2016). Their name, bacteriophages, is derived from the idea that they are “bacteria eaters.” Due to their bacteria-destroying nature, they have been used in phage therapy in which they…

Over many years, scientists have achieved the understanding of the human body. For example, how each system of the human body works, but most importantly, how they fail to work has led to different disease processes and the possible treatments. Although genetic research began long ago, it was not until 1990, when the Human Genome Project was introduced and successfully completed in 2003 (National Human Genome Institute, 2014). This project allowed scientists to understand the “sequences that…

The icosahedral structure is essential to viruses because it provides a stable, protective covering to protect the genome from any chemical or physical agents from harming it. In addition, the icosahedral shape is made up of identical subunits, the virus will better utilize its genome to encode proteins for the capsid. Finally, the last reason that I believe icosahedral structures have been favored by evolution is simply because they allow delivery of the genome by specific binding to external…

is caused by a virus. The inflammation can also happen on the underside of your eyelids. The blood vessels in the conjunctiva become inflamed, causing the eye to become red or pink, and often itchy. Viral conjunctivitis can be easily passed from one person to another (contagious). CAUSES Viral conjunctivitis is caused by a virus. A virus is a type of germ and can spread from one person to another. It can also be spread by touching objects that have been contaminated with the virus, such as…

Case study 1 Mr I is suffering from seasonal influenza as he shows symptoms including sneezing, headache, muscle ache, malaise, dry, chesty cough, fever, fatigue and weakness because he can hardly sit up. These are all the symptoms of seasonal influenza (NICE, 2015). Although symptoms of colds and influenza are very similar, but his symptoms developed within two days which is relatively fast, proving that he suffers from influenza instead of cold. As symptoms of influenza develop a lot faster…

There has been much thought in the scientific community about the polymorphism of human blood types and their genetic factors, and disagreement and uncertainty about details like which evolutionary mechanism blood types have followed over the course of their development and how one’s blood type and environment interact. Investigation and study of blood types has revealed many aspects in which certain blood types provide some advantage to their possessors, providing evidence that they were…

For the initial entry of the virus, the ephrinB2 domain is necessary. Once entered through micropinocytosis, protease cathespin L activates the virus (12). Nipah Virus can replicate very easily in human lung fibroblasts. It can infect the surrounding cells by either cell-to-cell spread or through release of infectious particles. When monocytes get infected, they can transmigrate through the blood brain barrier to infect the brain. This could be plausible if the monocytes were inefficient in…
