Gene Expression in Bacteria is Regulated Primarily By

Question

Gene expression in bacteria is regulated primarily by:
A) controlling the rate of DNA replication
B) protein modifications
C) protein degradation
D) transcriptional control
E) translational control

Accepted Answer

Gene expression in bacteria is primarily regulated at the transcriptional level, where the synthesis of messenger RNA (mRNA) from DNA is controlled. This allows bacteria to rapidly respond to environmental changes by altering the types and amounts of proteins produced.
