Exam 16: Control of Gene Expression

The lactose analog isopropyl- $\beta$ -D-thio-galactoside (IPTG)is often used to regulate gene expression systems in bacteria.IPTG does not act as a substrate for $\beta$ -galactosidase,but can bind to,and inactivate,repressor.In this case,IPTG serves as a(n)

Small RNAs can regulate gene expression.One type,called micro RNA (miRNA),acts by binding directly to

The p300/CBP (CREB-binding protein)coactivator proteins are histone acetyltransferases that help regulate the transcription of many genes.Based on this information,these proteins are involved in
