Quizplus · Accepted Answer

Transcription factors in eukaryotes typically have two distinct domains, a DNA-binding domain and an activation domain. The DNA-binding domain allows the transcription factor to specifically bind to a particular target sequence on the DNA, while the activation domain interacts with other proteins in the transcriptional machinery to promote or enhance gene expression. Some transcription factors also contain domains involved in repression of gene expression, but this is not as common as the presence of an activation domain.
