Question

multiple choice 10 points
what is the primary function of an operon in bacterial gene regulation?
to control the transcription of multiple related genes
to speed up protein synthesis
to prevent mutations from occurring
to initiate dna replication

Explanation:

An operon is a cluster of genes with a single promoter. Bacteria use operons to coordinate the expression of multiple related genes. For example, in the lac operon, genes involved in lactose metabolism are transcribed together. Transcription control is a key regulatory mechanism. Protein synthesis speed - ribosome activity and mRNA availability affect this more directly. Mutations - operons don't prevent them (mutations are random changes in DNA). DNA replication initiation - specific origins of replication and replication machinery handle this.

Answer:

To control the transcription of multiple related genes
