  • Double Helix Research Paper

    Structure of DNA: The Double Helix Introduction: DNA stands for DeoxyriboNucleic Acid. It is a type of Nucleic Acid, which has deoxyribose sugar in it instead of ribose. DNA has a double helical structure. By double helix, the meaning is two strands of polynucleotide running parallel and coiled around each other through hydrogen bonding. DNA is hereditary material in all the living organisms on this planet. The basic mystery behind its heredity nature resides in the same double helical structure…

  • Sickle Cell Anemia Effect

    Sickle Cell Anemia is an inherited blood disorder that mostly affects people of African ancestry, but it can also occur in other ethnic groups such as Middle East and Mediterranean descent (National Institute of Health). The disease affects the hemoglobin molecule in the red blood cells. Hemoglobin helps with carrying oxygen from the lungs and delivering it to different parts of the body. The mutation of this disease makes the cells become abnormal and irregular shaped. As a result, the abnormal…

  • Arsenic Vs Cadmium Essay

    Heavy metals are found toxic to humans as well as canines. Canines are much more susceptible to absorbing heavy metals than humans. One of the major effects of the heavy metals is reducing the metabolism in both humans and canines through accumulation of toxins. This experiment can provide evidence as to how much of the experimental toxin (arsenic and cadmium) affects cells’ metabolism when allowed to accumulate after 72 hours. In addition, different amounts of arsenic and cadmium (50 ppm, 100…

  • Cellular Respiration: Video Analysis

    Cellular respiration is a very interesting topic that we are currently learning about in our biology class. What makes this particular topic so remarkable are all of the different elements that work together for cellular respiration to occur in human beings and animals. In the video, “ATP & Respiration: Crash Course Biology #& 7.” (ATP & Respiration: Crash Course Biology #7. n.d.). The narrator does an excellent job of explaining the cellular respiration process in a very clear cut…

  • Dopamine Reaction Lab Report

    dopamine biosynthesis, do not function without coenzymes. The three coenzymes involved in the formation of dopamine are: tetrahydrofolic acid, used for L-tyrosine to L-dopa; Pyridoxal phosphate, used for L-dopa to dopamine; and NADH (Nicotinamide Adenine Dinucleotide + Hydrogen), used for the formation of tetrahydrofolic acid and pyridoxal phosphate. These three coenzymes are derivatives of vitamins either consumed or present in the…

  • Photosynthesis: What Is The Importance Of Photosynthesis?

    The energy currency for almost all living organisms is a compound called ATP, or adenosine tri-phosphate. This compound is made of up one adenine and three phosphate molecules which link together to form a structure like this: Adenosine Notice that the three bonds within this molecule become increasingly longer the farther away the phosphate is from the adenosine. This is to represent the fact that the bonds weaken as the distance between the adenosine and phosphates increases. This is…

  • Evidence Of Evolution Essay

    The DNA in living things is highly conserved. DNA has four bases that code for all differences in living things on Earth. Adenine, Cytosine, Guanine, and Thymine line up in a specific order and a group of three, or a codon, code for one of 20 amino acids found on Earth. The order of those amino acids determines what protein is made. Interestingly scientists have found that only…

  • Organic Macromolecule Essay

    nucleotides covalently bound together. Nucleotides contain a deoxyribose sugar, a phosphate group, and one of four nitrogenous bases. The four nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). To construct DNA’s double helix, hydrogen bonds form between two complementary nitrogenous bases. These bonds only form between adenine and thymine and between guanine and cytosine (“DNA”). DNA contains the instructions on how to create and build an organism. A gene is a…

  • Beta Cell Bio Research Paper

    Cell Biology Beta cells in pancreatic tissues are described as eukaryotic cells and not prokaryotic, this is because the cell is larger in size and there is a true nucleus present which contains DNA. In prokaryotic cell there isn’t a nucleus and the DNA is free within the cytoplasm. Also Beta cells have many organelles and there is mitochondria present, which in a prokaryotic cell there are fewer organelles and there aren’t any mitochondria present. Beta cells in the pancreatic tissue release…

  • Assignment 3: CS696 Programming Problems In Bioinformatics

    they are coiling around each other. DNA is made up from one of the four nucleotide, guanine (G), adenine (A), thymine (T), or cytosine (C). DNA strings are made up of alphabets {A, C, G, T}. 2. RNA strings: Known as RiboNucleic acid (RNA). Similar to DNA, RNA is also nucleic acid. But RNA usually found in the form of folded to it. RNA is also made up from one of the four nucleotide, guanine (G), adenine (A), uracil (U) and cytosine (C). RNA strings are made up of {A, C, G, U}. 3. Protein…
