Answer 1

Answer: Regulate gene expression

Answer 2

Activators and repressors are examples of factors a cell can use to - C. regulate gene expression.

Regulator proteins

These are the proteins that have the ability to influence the regions of a DNA molecule transcribed during transcription. A regulator protein that increases the rate of transcription is called promoter or activators and decreases are called repressors.

The proteins help in regulating gene expression by increasing or decreasing the rate of transcription.
