In the late stages of flagellum protein synthesis, the anti-sigma factor is exported from the cell so the sigma factor can promote assembly gene transcription, allowing the flagellum to be put together. Eukaryotic and archaeal promoters also need extra proteins to target the core enzyme to promoters: _______ _____________ _______. - ANSWER -general transcription factors The TFII complex works with RNA Polymerase ___ to form the ___-_________ complex. - ANSWER -II, pre-initiation ...

Stages of transcription initiation - ANSWER -- holoenzyme recognizes regulatory sequence in promoter and binds forming the closed promoter complex - unwind dsDNA to form open promoter complex - transcription initiates (RNA Pol generates short abortive transcripts that are unstable and released) - at 10nt in length, the complex is stable and turns from initiation to elongation Cycling of sigma during transcription - ANSWER -- as Pol transitions to elongation, sigma factor is relea...

How does mRNA secondary structure effect translation from a polycistronic message? - ANSWER -by blocking translation. Ribosomes must bind to linear mRNA in order to proceed with translation, however, if an ORF is in the shape of say, a double-stranded helix, the ribosome will be unable to bind at this location. Therefore, there may be more proteins synthesized from one ORF that is linear and unblocked compared to another ORF on the same mRNA that is not in a linear shape. H...

Negative Punishment - ANSWER -the removal of a stimulus to decrease the probability of a behavior's recurring. Time Out would be a negative punishment because you are subtracting from the time in the environment. Reinforcer - ANSWER -A stimulus that is either delivered or removed that will Increase the likelihood of that response occurring in the future Punisher - ANSWER -any stimulus or event that functions to decrease the likelihood of the behavior that led to it ...
