Nucleic Acids Competency 208.5.1 Melissa Kelleher, RN The Structure of DNA • DNA is composed of units called nucleoCdes, (Wolfe, 2000). • NucleoCdes are composed of a phosphate group, a deoxyribose sugar, and a nitrogenous base, (Wolfe, 2000). – Purines – nitrogenous bases that composed of two rings,

Genetically modified food is made by applying different genetic engineering technologies to raise the best in fruits, crops and vegetables etc. these techniques involve the cross breeding of different species of plants and even animals to produce the off-springs of specific traits. This is done such that the species with the best quality traits are cross bred. Although this methodology would seem beneficial but it is actually against the natural and normal breeding because GM involves interbreeding

It could be exciting to There are different types of twins that occur in not only to humans but to a variety of different types of mammals, they are either dizygotic or monozygotic. In the case of conjoined twins, they are monozygotic, or identical, and the highest incident is in humans (Kaufman, 2004). It occurs two weeks after fertilization or at the primitive streak stage where the twins get attached to one another. Conjoined twins have a common placenta, an amniotic as well as chorionic sac (National

Contrary to what many proponents of GMO labeling believe, GMOs actually bring with them many benefits, some of which are already being seen. With the increase of genetically modified corn and soybeans in the united states, the amount of chemical usage has been greatly reduced, and farmers have made more money because they don’t have to buy pesticides (Lusk and Miller 2). GMOs also have promising benefits for solving the problems of the future. Out of the 7.5 billion people in the world today, nearly

Biodiversity Define Biodiversity; Biodiversity is an ecosystem or certain habitat where there range of different animal species coexist with each other. (Biodiversity causes a healthy eco-system) ‘’The richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.’’(The Convention about Life on Earth, 2014) 1) Prevent Extinction; the larger the variety of animals that exist in the world the

DNA Replication, Translation, Transcription, and Death Cap Mushrooms Biochemistry – GRT1 Task 1 02/14/2015 (Wolfe, DNA Replication, 2000) (Wolfe, DNA Translation, 2000) A death cap mushroom, also known as Amanita phalloides, is a poisonous mushroom that can be detrimental to our health. When a death cap mushroom is ingested a toxic substance known as alpha amanitin is released into the body’s system. This toxin prevents protein production and leads to cell death (Santi, Luca, Caterina

whether viruses should be defined as live or not. They contain some of the structures and exhibit some of the activities that are common to the definition of organic life, but are missing others. Unlike viroids and prions, they contain both RNA and DNA. Scientifically they are classified in a place between supra molecular complexes and extremely simple biological entities. Viruses are composed of a single strand of genetic information encapsulated in protein. One of the most compelling arguments

Score: Activity no. __ What’s the Message I. Objectives: • Make a model to show how the order of bases in DNA determines the order of bases in mRNA. • Infer why the structure of DNA enables it to be easily copied. II. Materials: • crayons • 1/4 illustration board or long folder • scissors • paste/tape III. Procedure: 1. Use the patterns of the components of the DNA provided by your teacher. Color code phosphate = blue, deoxyribose sugar = green, ribose sugar = brown and nitrogenous

the virus attaches itself to the surface and the cell receptors draws the virus inside this called endocytosis. The virus which contains a genetic coding for enzymes is called integrase. Next the enzyme cut away at the diseased gene in the cell’s DNA and is replace with the virus therapeutic gene. With the new gene in place the cells start to make proteins to fight the disease. The dilemma of gene therapy is the clinical testing, even though the gene therapy might be working but the cell realizes
