: Biological Macromolecules & the Brain (4 pts)

Case studies look more closely at how a topic covered in class applies to issues in the “real world.” This case study will introduce you to the 4 major biological macromolecules first discussed in Chapter 3. In this case study, we will also explore forensic DNA analysis and a “cold case” that was recently solved through DNA analysis. We will continue to discuss the structure and function of the 4 major biological macromolecules - lipids, carbohydrates, proteins and nucleic acids (DNA and RNA) - throughout the quarter. o These assignments will help you think more critically about the news and other media you consume on a daily basis. o The case studies will help you to explore various topics within the field of cell biology and healthcare. o You will skillfully analyze the information that you receive and assess that information. Critical thinking is a life skill and it is the starting point for understanding yourself and the world around you. o These assignments will benefit you in a professional setting because employers value employees that can think critically, respectfully synthesize and express opinions, effectively communicate with people from different backgrounds, exercise ethical judgement, have high ethical standards, and possess cultural competency. Task: 1. Carefully watch the provided videos and refer to your slides and Chapter 3 of your textbook. 2. Formulate your thoughts and concisely answer the questions below. 3.

Upload this Word document containing your bolded answers directly into Canvas. Criteria for Success:  Always read all of the instructions.  Be prepared (carefully watch the assigned video. Pause it when necessary).  Answer all parts of all questions.  Include enough information that I know what you mean. Explain. Do not be vague.  Be curious about healthcare, science, ethics, and the world around you.  Be interested in how scientific research and progress is portrayed in the media.  Give your honest opinions. If I am asking for your opinion, I want your true opinion and you will not be penalized for your opinion.  Meet your deadline. Instructions: Watch TED-Ed video titled “How the food you eat affects your brain” and the SciShow video titled “How DNA Analysis Led Police to the Golden State Killer”. I am going to ask you questions from these videos and I want answers from these videos (not from random internet searches… please just watch the videos. They are less than 11 minutes long total). The first video may help you learn how to properly fuel your brain and the second This study source was downloaded by from CourseH on :46:02 GMT -06:00 video covers a relatively current even that you may already know something about and it may lead to you an interesting career path in crime scene investigation or forensics! (Who doesn’t love a good CSI show?) Answer the following questions:  Type your answers in the spaces below. Bold your answers.  You will upload this entire Word document directly to Canvas. 1. Watch the TED-Ed video titled “How the food you eat affects your brain” to learn more about the last three biological macromolecules. a.
