Carbon and the Molecular Diversity of Life Carbon: The Backbone of Life Important Concepts Carbon compounds are the basis of molecules essential to life. Carbon’s ability to form 4 covalent bonds provide the backbone for a diverse array of molecules. Biological molecules consist of carbon skeletons attached to common chemical groups. Living organisms consist mostly of carbon. Carbon forms complex molecules Proteins Nucleic Acids DNA/ RNA Carohydrates Lipids Experimental Approach Vitalism The idea that organic compounds are distinct from other chemical compounds and could only arise from within a living organism. Mechanism Is the view that all natural phenomena are governed by physical and chemical laws. Miller Experiment Small molecules present in atmosphere of the early Earth. Mixed with H20 Vapor Added an electrical spark The experiment supports the Mechanism Hypothesis.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
