GCD 3022 EXAM 3 QUESTIONS
COMPLETE AND CORRECT ANSWERS
\.repressors - ANSWERS-proteins that inhibit/decrease transcription,
bind to silencers
\.activators - ANSWERS-proteins that increase transcription, bind to
enhancers
\.transcription initiation - ANSWERS-most common way to regulate
gene expression is at this level
\.no - ANSWERS-[transcription occurs: yes or no] repressor protein, no
inducer
\.yes - ANSWERS-[transcription occurs: yes or no] repressor protein,
inducer
\.no - ANSWERS-[transcription occurs: yes or no] activator protein, no
inducer
,\.yes - ANSWERS-[transcription occurs: yes or no] activator protein,
inducer
\.yes - ANSWERS-[transcription occurs: yes or no] repressor protein, no
corepressor
\.no - ANSWERS-[transcription occurs: yes or no] repressor protein,
corepressor
\.yes - ANSWERS-[transcription occurs: yes or no] activator protein, no
inhibitor
\.no - ANSWERS-[transcription occurs: yes or no] activator protein,
inhibitor
\.trans-effect - ANSWERS-regulation occurs even though DNA segments
are not physically adjacent
\.cis-effect - ANSWERS-DNA sequence must be adjacent to the gene is
regulates
\.catabolism - ANSWERS-[catabolism or anabolism] typically inducible
, \.anabolism - ANSWERS-[catabolism or anabolism] typically repressible
\.translational repressors - ANSWERS-inhibit translation
\.block the ribosome, stabilize mRNA secondary structure - ANSWERS-
how translational repressors inhibit translation
\.antisense RNA - ANSWERS-regulate translation in prokaryotes via **
\.feedback inhibition - ANSWERS-final produce in a pathway inhibits an
enzyme that acts earlier in the pathway
\.allosteric - ANSWERS-contains two different binding sites
\.catalytic site (of alleosteric enzyme) - ANSWERS-binds to substrate
\.regulatory site (of alleosteric enzyme) - ANSWERS-site that binds to
final product of the pathway
\.transcription factors - ANSWERS-proteins that influence the ability of
RNA polyerase to transcribe genes
