Microbial Genetics Study Guide C. What is the function of RNA? D. Why is it critical that proofreading occur during DNA replication, but that proofreading is absent during transcription and translation? 7. A. In your own words, give a simplified definition as to what happens in transcription. B. Now, briefly outline the steps of transcription. Draw three basic stages of transcription using your piece of DNA from Question #2: 1. Original DNA molecule 2. Molecule half split with a few new RNA nucleotides added to show the start of transcription 3. Original strand of DNA and new strand of mRNA. C. Where does RNA polymerase bind to the DNA to begin transcription? Where does it terminate transcription? Which direction does it move along the DNA strand? 8. A. What is the overall purpose of mRNA made in the process of transcription? B. Where does transcription occur in prokaryotes? In eukaryotes? C. Where does the mRNA molecule move after transcription is complete? D. In your own words, what is a codon? E. Using your strand of mRNA transcribed above, what are the two codons and what amino acids do they represent?

    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.
