Question

a researcher is seeking to understand the relationship between an identified noncoding region close to the gene coding for adenosine deaminase. select two testable questions that would best help the researcher understand this relationship.

• do all noncoding regions affect protein synthesis?
• does changing the noncoding region affect production of adenosine deaminase?
• how close is the noncoding region to the gene coding for adenosine deaminase?
• why is there a noncoding region near this gene coding for adenosine deaminase?
• how does removing the noncoding region affect production of adenosine deaminase?

Explanation:

1. The goal is to find testable questions that directly examine the relationship between the specific noncoding region and the adenosine deaminase gene.

• "Do all noncoding regions affect protein synthesis?" is too broad, not focused on the specific pair.
• "Does changing the noncoding region affect production of adenosine deaminase?" directly tests if altering the region impacts the gene's product, which is testable and targeted.
• "How close is the noncoding region to the gene coding for adenosine deaminase?" is a descriptive question, not testing the functional relationship.
• "Why is there a noncoding region near this gene coding for adenosine deaminase?" asks for a causal explanation that is not directly testable in a functional relationship study.
• "How does removing the noncoding region affect production of adenosine deaminase?" directly tests the functional impact of removing the specific region on the gene's product, which is testable and targeted.

1. The two best testable questions are the ones that directly manipulate or change the noncoding region and measure the effect on adenosine deaminase production.

Answer:

• Does changing the noncoding region affect production of adenosine deaminase?
• How does removing the noncoding region affect production of adenosine deaminase?
