Unformatted text preview: 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....
