Question

Eukaryotic Transcription Factors (TF) can be described as:

a. Activators that recruit co-activators to initiate transcription of the gene

b. cis-acting transcriptional elements

c. proteins that interact with the promoter/enhancer regions via DNA binding domains

d. multimeric components of nucleosomes

Answer 1

eukaryotic transcription factors can be described as-

activators that recruit co-activators to initiate transcription of the gene

transcription factors are proteins that interact with promoter/enhancer regions via DNA binding domains.

enhancers increase the basal level of transcription which is initiated through the core promoter elements. it consists of array of binding sites for DNA binding transcription factors.

so a and d are correct answers.

transcription factors are trans acting elements that may either activate or inhibit expression of gene.
