ROLE OF BACTERIOPHAGES IN GENETICS AND MOLECULAR BIOLOGY INTRODUCTION AND DISCOVERY: A bacteriophage is any one of a number of viruses that infect bacteria. Bacteriophages are among the most common biological entities on Earth. The term is commonly used in its shortened form‚ phage.Typically; bacteriophages consist of an outer protein capsid‚ enclosing genetic material. The genetic material can be ssRNA‚ dsRNA‚ ssDNA‚ or dsDNA along with either circular or linear arrangement. Bacteriophages are

meaningful” (Wald 45). These words were spoken by a Nobel Prize winning biologist and Harvard professor‚ George Wald‚ in a lecture given in 1976 on the Dangers of Genetic Engineering. This quotation states that incredible inventions‚ such as genetic engineering‚ are not always beneficial to society. Genetic engineering is “altering the genetic material of cells and/or organisms in order to make them capable of making new substances or performing new functions” (Wald 45). It is also one of

Genetic engineering in general Pros|Cons| With the discovery of DNA and unravelling the genetic code it contains‚ molecular biologists have finally come close to understanding what determines the form and function of organisms and can use this to design organisms at will. This is illustrated by the experiments on the transgenic fruit fly which has eyes on its antennae (Walter Gehring‚ Basel Biocentre‚ Switzerland. see the year 1994 in http://www.ifgene.org/history.htm ). This new technology will

Gene Modification From a Libertarian Perspective Over many years‚ the idea of genetically modifying human embryos has been an extremely controversial topic. A global network of stem cell researchers named Hixton Group released a statement claiming that genetic modification is essential to gain basic understanding of the biology of early embryos. Being able to modify and study embryos would bring tremendous value to science. Although the group didn’t particularly encourage changing embryos for personal

“Ghost in Your Genes”- when hearing this I thought of something unknown‚ overtaking your body‚ or at least a part of your body. The movie‚ Ghost in Your Genes‚ presents an experiment done in the 1990s‚ called the Human Genome Project (Ghost in Your Genes). During this project‚ researchers were able to discover the chemical structure of each gene and overall they hoped to find a cure for all diseases‚ such as alzheimer’s and autism (Ghost in Your Genes). It was also found out that humans‚ surprisingly

Portfolio Assessment in Social Studies What is a portfolio? A portfolio is a systematic collection of entries‚ over a period of time (e.g. from P4 GEP to P6 GEP). An entry is typically made up of 3 parts: (i) an artefact‚ (ii) a commentary‚ and (iii) a reflection. Please refer to the table below for more details. |Artefact |Commentary* |Reflection** | |Self-created:

Niccol’s film‚ “Gattaca” describes a world where genetic engineering has become norm. Based on a society where intellect is built not on diligence and determination but instead genetic determinism‚ the film explores oppression in society‚ displaying just how easily corruption can become. Race‚ sex‚ height and gender; discrimination of which is unseen in the world of Gattaca.
