DNA/RNA/Protein for prokaryotes. Animations to know: www.mhhe.com/nester6 Chapter 7: DNA replication Bi-directional DNA Transcription factors mRNA synthesis How translation works Processing of Gene Information: Prokaryotes vs. Eukaryotes Trp operon I. Semi-conservative replication (Fig. 7.4) A. Each new strand contains one molecule of the parental strand and one molecule of copied DNA called the daughter strand. B. DNA Nucleotide (Fig. 2.22) Deoxyribose sugar/phosphate backbone. C. New strand is always synthesized in the 5’ to 3’ direction (Indicates which base on the sugar molecule the phosphate is attached) (Fig. 2.23, Fig. 7.5) D. Replication fork starts at the origin of replication (Fig. 7.6 and Table 7.1), require Primase to start replication. E. Helicase unwinds double strand. DNA gyrase allows the resulting tension in the double helix to be released. F. DNA polymerase requires a primer to start synthesizing DNA. Primase (an RNA polymerase) makes a small RNA primer to allow synthesis to begin.

    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.
