Document Summary

Biology 1aa3 - textbook notes - chapter 3. Idea of chemical evolution first introduced by alexander oparin in 1923 and then again by jbs haldane: can now be considered as an official scientific theory, the theory consists of two components: Pattern: increasingly complex carbon-containing molecules formed in the atmosphere and ocean of ancient earth. Process responsible for pattern: conversion of energy, from sunlight and other sources , into chemical energy in the bonds of large, complex molecules. This theory has been modified as well since more research has been conducted and new information has been recovered. And nitrogenous bases: these molecules accumulated in shallow waters of ancient ocean --> complex solution formed called. Prebiotic soup: mid sized molecules joined to form large molecules found in cells today such as proteins, nucleic. Acids and complex carbohydrates: these large molecules are made up of distinctive chemical subunits (monomers). Proteins - made up of amino acids. Nucleic acids - made up of nucleotides.
