Document Summary
Concept 1. 1: living organisms share common aspects of structure, Typically are composed of a common set of chemical parts. Depend on intricate interactions among structurally complex parts. Contain genetic information that uses a universal code to specify how proteins are assembled. Convert molecules obtained from their environment into new molecules. Share structural similarities among a fundamental set of genes. Evolve through gradual changes in their genetic information. Nucleic acids: molecules that could reproduce themselves and also contain the information for synthesis of large molecules with complex but stable shapes. Cell: a unit of complex proteins and other biological molecules enclosed in a membrane. Prokaryotes: single cells containing genetic material and other biochemical structures enclosed in a membrane (bacteria is a descendant) Photosynthesis: a set of chemical reactions that transforms the energy of sunlight into chemical-bond energy of the sugar glucose and other relatively small biological molecules.
