  • The Origin Problem In Research

    The Origin Problem Since the time of Darwin, naturalists have attempted to explain how life formed through purely natural causes. Some naturalist models argued that either DNA or a protein provided the first possibility for life. However, problems with these models became evident as the researcher’s knowledge of DNA grew. The researchers discovered DNA relies on proteins for transcription and translation, but functional proteins cannot form without the information stored in DNA. The solution…

  • Diffusion Of Water And Osmosis Experiment

    Although, this concept can sound complicated it simply means that whatever is being discussed moves from an area where there is a high concentration of the substance to an area where the concentration is lower. This type of process requires no ATP (Adenine triphosphate) which is the major source of energy on the cellular level. Osmosis refers specifically to the diffusion of water. The tonicity or internal tension of a cell is heavily affected by osmosis. If a cell is placed in a solution with…

  • Symbolism In Gattaca

    Guanine, Adenine, Thymine, Cytosine are the four nucleotide bases of DNA. The clever title, of the futuristic movie revolving around genetic engineering, “Gattaca”, is a DNA sequence. The symbolism, as within the title, continues throughout the thought provoking film. DNA is like the instructions used to develop life. However, in the film, DNA is also a prime determinate of social class. Vincent Freeman is a baby of faith, conceived by means of natural reproduction. His parent’s decision, to…

  • Huntington's Chorea Case Study

    Huntington’s Chorea, more commonly known as Huntington’s disease, is a progressive hereditary neurodegenerative disorder that presents in mid-life, affecting an individual’s cognitive, emotional and motor abilities (Warby, Graham, & Hayden, 2014). Huntington’s disease was named after an American Physician by the name of George Huntington, who first documented the disease in 1872. In his findings, he described the disease as Hereditary chorea. In Greek terminology, the word Chorea means “to…

  • Why Biology Is Important

    What comes to mind when someone asks “What is biology”? Do you think of tiny cells spread throughout your entire body helping you stay alive, your DNA, or maybe plants? Biology is simply the study of living organisms. We learn by studying where living organisms come, from, where it has been, who or what were its ancestors, what it has used as food and even if there are any diseases or degenerations present. Biology helps us treat diseases, create vaccines, aid in better nutrition and has even…

  • Chloroplast Research Paper

    Chloroplast are found in plants, they are responsible for the metabolism of energy to produce food for plants by breaking down Carbon dioxide, water and sunlight through a process called Photosynthesis. Once Carbon Dioxide enters a plant through stomata pores in a plant, water is absorbed through the roots of a plant and sunlight captured by chlorophyll pigments inside the chloroplast which is actually inside the thylakoids. It 's the russian doll complex., it is within the chloroplast that…

  • Essay On Dna Profiling

    making it a turning point in history. Scientific Foundation of DNA Profiling The DNA (also known as Deoxyribonucleic acid) in cells is formed of two long strands that wrap around each other. There are four different types of bases in DNA, A (adenine), C (cytosine), G (guanine), T (thymine). These bases join together, A with T and U with G, to form a structure that looks like the twisted steps of a…

  • Dna's Four Biological Tasks

    that make each species unique is a code often referred to as Deoxyribonucleic acid or DNA. In every cell in an organism DNA can be found in the cell’s nucleus. mRNA a replication of DNA leaves the cell’s nucleus and journeys to the mitochondria. Adenine (A), Guanine (G), Cytosine (C) and Thymine (T) are the four coded chemical bases that the DNA uses to store information. Three of these bases code for a triplet of a codon. DNA’s four chemical bases each have a pair; A with T and C with G. Each…

  • Haemoglobin Lab Report

    transfer of electrons along the mitochondrial inner membrane enables this process. Four protein complexes take part in this process and pump out protons. Extrusion of 6 protons occurs for every 10 electrons that move along the membrane. Nicotinamide adenine dinucleotide phosphate (NADPH) acts as the first electron donor. The other proteins - Ubiquinone and Co-enzyme Q - transfer the electrons to the final acceptor. The eventual acceptor of the electron is oxygen, which forms water by combining…
