Biol 101 21 February 2008 Code of each RNA is read three letters at a time Test o Cell respiration starts test topics o No detail on photosynthesis, but on cellular level with interaction between products and reactants of the two o Lots of genetic problems o Some cell division focusing on meiosis o Information about molecular genetics and protein synthesis Protein Synthesis (ch. 13) o Protein Synthesis: initiation m-RNA attaches to small subunit Exposed AUG > t-RNA with amino acid Large subunit attaches o Elongation 2 nd t-RNA arrives Peptide bond forms between amino acids Empty t-RNA leaves, other moves over o Happens on both the free ribosomes and ribosomes on the Rough ER o Termination Stop code causes binding of releasing factor

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
