BIO 210 EXAM 1 STUDY GUIDE What 3 functions of RNA mediate the "coordinate cellular activity" function of DNA - CORRECT ANSWERS-1. Transfer information from DNA to Protein Synthesis Machinery (ribosome) 2. Transfer amino acids to Protein Synthesis Machinery 3. Form peptide bonds- ribosomal RNA Name the 5 biological themes that will be encountered in this course - CORRECT ANSWERS-1. Mechanistic doctrine 2. Cell Theory 3. Central Dogma of Biology 4. Gene theory of inheritance 5. Cellular Evolution What is it about the mechanistic doctrine that makes biology the most inter-disciplinary scientific discipline - CORRECT ANSWERS-It draws from all other sciences and cells can be studied by chemical and physical methods What are the three statements of the cell theory - CORRECT ANSWERS-1. All organisms are composed of cells 2. All cells come from pre-existing cells 3. Chemical reactions responsible for life take place within cells If the latest Mars rover, Curiosity, found a mummified organism and demonstrated it was composed of cells, would that increase the generality of the cell theory - CORRECT ANSWERS-No, because it would confirm that all organisms are composed of cells In Crick's Central Dogma information can flow back and forth between two macromolecules but only one way between the second and third. Name the information flow that is uni-directional - CORRECT ANSWERS-RNA- Protein Mendel proposed pairs of inherited factors that we now call genes. What is a current definition of a gene - CORRECT ANSWERS-Organismal characteristics determined by discrete segments of DNA
