WebbGenes involved in the same cellular process are often clustered together in an operon whose expression is controlled by an upstream promoter. Generally, the activity of the promoter is strictly controlled. However, spurious transcription undermines this strict regulation, particularly affecting large operons. The negative effects of spurious … WebbOnly when lactose and glucose are both missing do the genes express. The catabolite activator protein and lac repressor, which control the operon, are activated and inactivated in response to the amounts of glucose and lactose. The lac repressor prevents the operon's transcription. Differentiate horizontal and vertical gene transfer.

Both prokaryotic and eukaryotic ribosomes can be broken down into two subunits, one large and one small. The exemplary species used in the table below for their respective rRNAs are the bacterium Escherichia coli (prokaryote) and human (eukaryote). Note that "nt" represents the length of the rRNA type in nucleotides and the "S" (such as in "16S) represents Svedberg units.
