Document Summary

Proteins made up of amino acids, and the difference in structure and function are due to the differences in side chain composition. Chemical evolution began with production of small organic compounds such as h2co, H2c0 and hcn and other molecules combined to form amino acids, sugars, and nitrogenous bases which accumulated in ocean creating the prebiotic soup (monomers) form. The various amino acids, sugars and nitrogenous bases combined to macromolecules; proteins, nucleic acids and carbohydrates. Life started when one of these molecules gained the ability to self-replicate by the using the chemical reactions it could control. Antibodies protein attack and destroy viruses and bacteria. Hormones; act as signals coordinating the activity of cells. Moving substances across the membrane and throughout the cell body. Stanley miller wanted to recreate ancient earth in terms of the elements present in the atmosphere; mainly co2, nh3, ch4, which were contained in a large flask.
