Biology Study Group #2 Midterm #2 Don’t need to know the steps of the citric cycle or enzymes…just know what is produced Know what each process makes and if it is anerobic or aerobic. Photosystem I and Photosystem II…PS II the electron is excited at 680nm and in PS I it gets excited at 700nm. Gets excited at 2 different wavelengths. On the chloroplast. Somatic cells: body cells, everything except eggs and sperm, goes through mitosis, not meiosis (eggs and sperm) Haploid/Diploid: Diploid is all body cells, haploid, eggs and sperm (one set of chromosomes). Mitosis produces more diploid cells. Meiosis produces more haploid cells. Haploid: half the amount of chromosomes… DNA Replication: unwinds the DNA (helicase), DNA primase puts the RNA primer onto the DNA strand. DNA polymerase III only attaches to the 3 prime end. RNA primer is there because DNA polymerase can only add onto existing DNA. Gets to a termination sequence and stops. Lagging strand—adds discontinuously…DNA polymerase adds onto the 3 prime end and keeps going till it gets to an RNA primer…Okazaki fragments are DNA pieces on the lagging strand.

    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.
