Individual bacteria respond to environmental change by regulating their gene expression. CSCOPE. Unit: 08 Lesson: 01. There are hundreds of different types of cells in your body, and each type has a unique function. We’re going to compare some different types of cells to see how much they have in common. . RNA can destabilize mRNA. Single-stranded RNA can affect gene expression. Double-stranded RNA can affect gene expression. All of above. . Before their study, it is known that. Single stranded RNA can cause RNA interference. Controlling gene expression is often accomplished by controlling transcription initiation..
