A reversion: change in the same locus that was mutated. ie: gene mutates from “A” to “a” (mutation, induced by mutagens, radiation, mistake, chemicals, etc.), the reversion is when it goes back to “A” Suppression is a second gene “B.” Mutation “B” > “b.” Suppressor mutation is when the “B” suppresses the mutation, and when it’s “b” the mutation is seen. Reporter gene: (no significance to CAT, which is a reporter gene). One uses CAT (or reporter gene) to monitor the activity of the promoter in question. [Question 4 on practice test]: Assume there’s an element between B & C that acts positively on transcription (turning it on). If one graphs the amount of transcription, (approximate numbers) A = 90%, B = 90%, C = D = E = 20% (bar graph). Upstream = 5’ end Pyrosequencing: novel technology, with which you add bases. Take a big strand and one adds a base pair, then another, then another, etc. Whichever dNTP gets added, that base gets incorporated into the strand, and pyrophosphate is released.

    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.
