A student is studying the following model of DNA.

Question

A strand of DNA that has exons and introns. The exons are labeled as coding regions. The introns are labeled as non-coding regions.

The student learns that some of the non-coding regions have a high concentration of repressors bound to them.

Which question should the student ask to further understand the role of these non-coding regions in gene regulation?

(1 point)
Responses

How are these non-coding regions transcribed into mRNA

Do these non-coding regions affect the structure of the DNA double helix?
Do these non-coding regions affect the structure of the DNA double helix?

What are the sequences of these non-coding regions, and how do they compare to known repressors?
What are the sequences of these non-coding regions, and how do they compare to known repressors?

How do these non-coding regions interact with DNA polymerase during replication?

Answer 1

The best question for the student to ask to further understand the role of these non-coding regions in gene regulation is:

What are the sequences of these non-coding regions, and how do they compare to known repressors?

This question focuses on the specific sequences of the non-coding regions, which is crucial for understanding how they might function in gene regulation, particularly in relation to the binding of repressors. Knowing the sequences may elucidate their regulatory roles and how they might interact with proteins involved in transcriptional regulation.
