In eukaryotes, different groups of proteins regulate transcription initiation. classify all of the transcription-associated proteins and protein components by their role in transcription. initiates transcription increases transcription decreases transcription coactivator activator repressor general transcription factor

Proteins named transcription factors, help set specific genes on or off by binding to the DNA.

Explanation:

A co-activator is the type of transcription factor that binds to the activators to increase the process of transcription.An activator is the type of transcription factor that increases transcription.A repressor is the type of transcription factor that decreases or prevents the transcription by blocking the RNA polymerase to the promoter. A general transcription factor, also known as a basal transcription factor, is a type of transcription factor that initiates transcription.
