Which of the Following is an Example of Post Translational

Question

Which of the following is an example of post translational regulation in prokaryotes?
A) Sterically blocking the ribosome
B) Phosphorylation of an enzyme
C) Incorporation of antisense RNA
D) Altering the structure of the mRNA

Accepted Answer

Post translational regulation refers to modifications or regulatory events that occur after the translation of a protein. In prokaryotes, phosphorylation of enzymes is a common form of post translational regulation, allowing for the activation or deactivation of specific enzymes. Options A, C, and D are not examples of post translational regulation but rather refer to events that occur during transcription or translation. Sterically blocking the ribosome occurs during translation initiation, incorporation of antisense RNA occurs during transcriptional regulation, and altering the structure of mRNA also occurs during transcription.
