Select all statements that correctly describe posttranscriptional gene regulation. Check All That Apply The activity of CRP is regulated posttranscriptionally: CRP changes conformation when bound to an effector. An antisense RNA reduces transcription of an E. coli mRNA that encodes the toxic protein SymE. A stem-loop structure that blocks access to a ribosome binding site is disrupted at high temperatures, allowing translation to occur. CRP binds to the lac promoter. RNA-Seq is used to find all the mRNAs that are regulated posttranscriptionally in a specific cell.
