The Critical Step in the Regulation of Most Bacterial Genes

Question

The critical step in the regulation of most bacterial genes occurs _____________.
A) during transcription
B) at the release of mRNA
C) during translation
D) posttranslationally
E) during replication

Accepted Answer

The critical step in the regulation of most bacterial genes is during transcription, which is when the DNA sequence is transcribed into mRNA by RNA polymerase. This is the point at which most regulatory mechanisms operate, such as transcription factors binding to regulatory sequences on the DNA or riboswitches in the mRNA.
