Question
A student is studying the following model of DNA.

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?

Answer 1

The best question for the student to ask in order to further understand the role of non-coding regions with a high concentration of repressors bound to them 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 likely play a critical role in their function. Understanding the sequences can provide insight into how these regions may interact with repressors and affect gene expression.
