Genes are arranged in co-transcribed clusters called operons.

Read-through transcripts: Read-through transcripts are also known as conjoined genes or co-transcribed genes.

To determine whether actA itself, plcB or other co-transcribed downstream regions are involved in actin assembly, mutations in the appropriate genes were generated.

Bacterial 16S ribosomal RNA, 23S ribosomal RNA, and 5S rRNA genes are typically organized as a co-transcribed operon.
