Hi, everyone. Let's take a look at this practice problem together. Steroid hormones like cortisol and estrogen often bind to receptors located within the cytoplasm or nucleus. The hormone receptor complex acts as a, the answer options are a promoter. B terminator C transcription factor and D silencer. So, recall what each of these answer options is. And if we know their functions, we can quickly narrow down the answer right off the bat. Note that a promoter, a terminator and a silencer are all specific DNA sequences. A promoter is where protein combine DNA and start transcription. A terminator is a specific DNA sequence that signals the stop of transcription. And a silencer is a regulatory DNA sequence that can prevent transcription. So options A B and D are types of DNA sequences. Now, the steroid hormone receptor complex is not a DNA sequence and does not act as a DNA sequence. So options A B and D are all incorrect answer. Choices. A transcription factor. Option C is a protein that combin DNA sequences to control the rate of transcription. So your hormone receptor complex acts as a protein. The correct answer therefore is option C transcription factor All right, everyone. I hope you found this helpful and I'll see you soon for the next practice problem.
