Each transcription factor usually has at least two domains that mediate different aspects of their function. What are they?
A)the DNA-binding domain and the activation domain
B)the activation domain and the repression domain
C)the DNA-binding domain and the repression domain
D)the RNA-binding domain and the activation domain
E)the RNA-binding domain and the repression domain

Question

Quizplus · Accepted Answer

The DNA-binding domain is responsible for recognizing and binding to specific DNA sequences, while the activation domain interacts with other transcription factors and components of the transcription machinery to activate gene expression. Some transcription factors may also have a repression domain that interacts with co-repressors to inhibit gene expression. However, the question specifies "usually," and therefore the most common and essential domains are the DNA-binding and activation domains.
