Question

Transcription factors in eukaryotes usually have DNA-binding domains as well as other domains that are specific for binding other molecules.T/F

Answer 1

True.

Step-by-step explanation:

Proteins called transcription factors bind to certain DNA sequences to control the transcription of genes. Transcription factors in eukaryotic cells often feature a DNA-binding domain that selectively binds to particular DNA sequences. They also possess additional binding domains designed specifically to bind substances like proteins or RNA. Transcriptional regulatory domains are the name given to these domains. They control the activity of transcription factors by attracting other proteins, chromatin-modifying enzymes, or the RNA polymerase II holoenzyme. The specificity and activity of the transcription factor are determined by the interaction between the DNA-binding domain and the transcriptional regulatory domains.
