Answer 1

Transcriptional regulators are proteins that bind to specific DNA sequences to regulate gene expression. They can coordinate and assemble into transcriptional complexes to control gene expression. Some transcriptional regulators have activation domains while others have repression domains.

Step-by-step explanation:

Transcriptional regulators are proteins involved in regulating gene expression by binding to specific DNA sequences. They have a DNA-binding domain that interacts with regulatory elements in the major groove of the DNA double helix. Transcriptional regulation is typically specific, meaning each gene is regulated independently, but multiple transcriptional regulators can coordinate and assemble into transcriptional complexes to control gene expression. Some transcriptional regulators have activation domains that enhance gene expression, while others have repression domains that suppress gene expression.
