What role do transcription factors play in gene expression?

Step 1: Understand that genes are segments of DNA that contain instructions for making proteins.
Step 2: Know that transcription is the process where the information in a gene is copied to make RNA.
Step 3: Learn that transcription factors are special proteins that help control this process.
Step 4: Realize that transcription factors can bind to specific parts of the DNA near a gene.
Step 5: Understand that when transcription factors bind to DNA, they can either help (enhance) or block (inhibit) the transcription of that gene.
Step 6: Conclude that transcription factors are essential for regulating which genes are turned on or off in a cell.
