The expression of genes required for biofilm formation occurs only after a cell has attached to a surface that is suitable for biofilm development.What is this type of gene expression called?

Question

Quizplus · Accepted Answer

The type of gene expression described is induction, because it is triggered by the presence of a specific signal (attachment to a suitable surface) and results in the activation of genes required for biofilm formation. Attenuation involves premature termination of transcription, feedback inhibition involves regulation of enzyme activity, repression involves blocking gene expression, and inhibition refers to a general decrease in biochemical activity.
