Gaia Theory and All Life is Connected

The concepts of an interconnected earth are intriguing and measurable. As a botanist and microbiologist I have studied symbiotic relations that range from parasitic to symbiotic. Many indigenous people have understood these concepts longer than modern scientists. The Lakota Sioux state: “Mitakuye Oyasin,”which means, “To all of my relations.” It is a prayer of oneness and harmony with all forms of life: people, animals, birds, plants, insects, and even rocks. It is a reminder that we all share a common kinship within the hoop of life. Our bodies are composites of bacteria, and within our cells are remnants of ancient bacterial cells that are now mitochondria. Dr. Lynn Marguelis a famous botanist, and suppoter of James Lovelock Theory of Gaia states: "The only individuals on the planet are bacteria."

Mysterious DNA-"A historical perspective"

March 19-20, 2012



Academic Goal: Historical Examination of DNA Function & Structure.

Biologists in the 1940's were skeptical about DNA's involvement as genetic material based on the simplicity of its chemistry. Composed of only four types of nucleotides (Adenosine, Guanine, Cytosine and Thymine) that are linked covalently into a polynucleotide chain (a DNA strand) with a sugar-phosphate backbone from which the bases (A,C,G and T) extend. Years of research, from a variety of scientists contributed to our current understanding about the "Thread of life."

    DNA Data Abstract

    The purpose of this assignment was to get a better understanding of how DNA came to be such a bit thing. The four compounds that make up DNA are known as Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). Below there is a chart using eight organisms that have DNA and it tells the percent that it uses A, T, G, and C.
    Organism A T G C
    Mycobacterium Tuberculosis 15.1 14.6 34.9 35.4
    Yeast 31.3 32.9 18.7 17.1
    Wheat 27.3 27.1 22.7 22.8
    Sea Urchin 32.8 32.1 17.7 17.3
    Marine Crab 47.3 47.3 2.7 2.7
    Turtle 29.7 27.9 22.0 21.3
    Rat 28.6 28.4 21.4 21.5
    Human 30.9 29.4 19.9 19.8

    It was interesting to learn about DNA in different organisms and the patter it has on them. We added up the totals in A, T, G and C, we found that as you add the colums up the total gets lower and lower each time. As we keep learning about DNA this year, we hope to find out why it changes so desperately. But it was cool to see how much DNA showed up in all these organisms.
