Concepts related to biological change and evolution such as: o How DNA and protein sequences are used to infer evolutionary relationships among organisms o The concept of natural selection o Evolutionary theory and how genetic change among individuals of populations is the raw material for evolution of new forms Genetic principles such as: o Mendal’s laws of heredity and how they relate to the movement of chromosomes to gametes during meiosis for determination of traits such as sex o The chemical and structural properties of DNA in heredity and protein synthesis o How recombinant DNA technology allows scientists to analyze the structure and function of genes Living systems classification related to: o How multicellular organism have a variety of specialized cells, tissues, organs, and organ systems that each perform specialized functions and integrate to make a functional organism o How an organisms internal and external structure, their development, and relatedness of DNA sequence are basis for their classification Function and structure of cells such as: o Knowing that all living systems are composed of cells, which are the fundamental units of life, and that organisms may be unicellular or multicellular o Knowing the importance of both water and the element of carbon to cells, and further understand the important types of macromolecules that are different in chemical properties with specific functions o The diversity and unity among cells o Knowing that there are different types of cells (prokaryotic and eukaryotic), but all share the same characteristics o How multicellular organisms consist of different types of cells that perform different functions o The difference between plant and animal cells that have different cellular specialization suited to the organism’s lifestyle o The processes of cell division (mitosis and meiosis) particularly as those processes relate to production of new cells and to the passing of genetic information between generations o How in eukaryotic cells, the organization of DNA into chromosomes is key to both duplication and distribution of the genetic information to new cells or organisms o That in order to be alive, cells must exchange materials with their environment or with other cells o That cells transform energy for one form to another through the processes of photosynthesis and respiration o How these processes lead to the production of ATP o The chemical reactions involved in cell functions o How such exchanges involve a variety of mechanisms for transporting materials across a membrane, including diffusion, osmosis, and transport involving specialized membrane proteins
