1. Macromolecules affected by Sickle Cell a. Hemoglobin: When the body is infected by Sickle Cell Disease‚ the primary structure of Hemoglobin is mutated. In the amino acid sequence‚ valine is substituted for glutamic acid causing sickle cell disease. This single mutation will eventually cause the entire protein to divide itself. b. Lipids: The lipids in the membrane of the cell are altered by sickle cell disease. Those who suffer from the disease have defective fasting lipid metabolism. This has

Correct Use of the Scientific Method and an Experiment with Macromolecules I. Objectives In this lab‚ students will: a.) Learn how to utilize the Scientific Method to develop a testable hypothesis b.) Generate an effective experimental design from a hypothesis c.) Understand the chemical differences between different macromolecules and how these differences can be used to design tests for each molecule. d.) Identify macromolecules in solutions using chemical analyses. e.) Practice recording

microfilament. Therefore‚ I got wrong in some multiple choices of this midterm. I went back to the notes and read them again after seeing my midterm which can help me to clarify and solidify my understanding. I also learned the structure of different macromolecules. It seems like such a tip as I learned these in Biology 12‚ but‚ there is additional knowledge of applying those structures. I found it’s interesting to recognize those structures through different functional groups. In this class‚ so far‚ I used

different amino acid‚ causing a mutation that could devastate the organism. Recently‚ scientists have discovered a new method to edit and repair DNA that could hopefully complement the existing method of CRISPR. DNA is a type of nucleic acid‚ a macromolecule found within a cell. DNA itself consists of two strands of nucleic acid in a double helix structure. Each of these strands consists of nucleotides‚ which in turn are made up of a pentose sugar‚ a nitrogenous base‚ and a phosphate group. The “code”

Associate Program Material DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information‚ composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The

P1 – Anatomy & Physiology Outline the functions of the main cell components Cell Membrane; in the human body there are millions of cells‚ for every cell in the body it is surrounded with a cell membrane also known as plasma.The cell membrane separates the interior of all cells to the outside environment. The outer layer or the cell controls the movement which goes in and out of the cell. The cell membrane holds the cell together‚ but has very tiny holes to allow products to move in

for the energy demands he was about to place on his body? He simply prepared his mind mentally and went through a lot of physical training. He also gained 16 pounds of body fat. 2. How did his body manage his fuel reserves? What macromolecules did his body look to first for energy? What did his body do when this resource ran out? It rationed them the best it could. It looked for calories first‚ and when this ran out he started to use his body fat as energy.
