CHEM 120 Week 7 Discussion: Flow of Genetic Information - Protein Initial Post Instructions In the news, we often hear examples of how DNA or the transfer of genetic information impacted someone's l ife. Examples range from DNA fingerprinting to genetically engineered organisms to an individual with a genetic disease. In each of these scenarios, the structure of nucleic acids and the flow of genetic information through mRNA to protein are involved. Using an example from the news or a scholarly ...

CHEM120 Week 7 Concepts: Biochemistry – Download For Revision And Improve Your Grades LIPIDS In this concept, we will discuss one class of biological polymers called lipids or fats. You might be f amiliar with this class of biopolymers, which are found in butters and oils. We will discuss saturated and unsaturated fats, and what those terms mean for the molecule's structure as well as its properties at room temperature. 1. Which of the following is a source of lipids? • Sugar, fruits, and b...

OL Lab 12: Introduction to Food Macromolecules Learning Objectives • Identify the types of macromolecules found in food • Identify the structure of carbohydrates, proteins, and lipids • Detec t macromolecules in food samples Introduction Macromolecules are very large molecules created by the polymerization of small units called monomers. Most of the macromolecules are present in everyday life, for instance in food. Learn about biological macromolecules There are several types of biological...

OL Lab 13: Protein Synthesis Part 2: Report and Reflection Purpose: Describe in complete sentences and in your own words, the purpose of this experiment. The purpose of this experiment is to lear n about the protein synthesis process. The purpose was to also learn about the devices used to test samples of urine in the lab, to decide whether illicit drugs were being used by athletes to enhance their performance. Observations: Record three observations from the simulation. I learned that ACTG is f...

Week 6 Discussion: Radiation Hello everyone, For this weeks discussion I will do option 2 on the topic of Uranium- 238. Uranium-238 is the most common isotope of Uranium yielding 99.2 percent wit hin natural uranium. Uranium- 238 has 92 protons and 146 neutrons. It was also recorded that it has a half- life of 4.5 billion years. a. Uranium- 238 is an ionizing radiation. b. Uranium- 238 gives off alpha particles which are not effectively penetrating so s long a its rays are found outside of the b...

Initial Post Instructions The Discussions in this course are set up deepen your understanding of the material as you make real world connections and employ creative thinking. To get the most from the se discussions, full engagement is expected on the part of the student. Be sure to stop by the discussion section frequently, not only to post, but to read the postings of your peers and instructor. Engaging with your peers and learning together is key to this experience. For your initial post, choo...

CHEM120 Week 6 Discussion: Radiation – Radioactive Isotope: Cobalt-60 (Option 1) Option 1 Cobalt-60 a. What type(s) of radioactive decay does your isotope undergo? Radioactive decay occurs when an unstable nucleus changes into a stable nucleus by emitting radiation. The cobalt-60 isotope undergoes a beta decay and produces gamma rays as it decays. The half-life for cobalt-60 is 5.27 years. This is how long the decaying process takes to get to Nickel-59, a more stable isotope ("Cancer Therapy,...
