In this chapter, we focused on the translation of mRNA into proteins as well as on protein structure and function. Along the way, we found many opportunities to consider the methods and reasoning by which much of this information was acquired. From the explanations in the chapter, what answers would you propose to the following fundamental questions: How do we know that the structure of a protein is intimately related to the function of that protein?

Hey everyone. Let's take a look at this question together. Any form of damage or alteration of this protein structure results in irreversible changes. So let's recall what we know about the different types of protein structures. To figure out if any of the following, sustained any kind of damage or alteration would result in irreversible changes. So we know that when we're talking about those protein structures, we have that primary secondary tertiary and co ordinary with that primary being the most important because it is that initial protein structure, which means that if the primary structure had any damage or alteration, it would result in those irreversible changes. So answer Choice A is the correct answer because if any of the secondary tertiary or co ordinary structures sustained minor damage, they would simply re fold back to their original shape. And when we're talking about that sustaining the minor damage or alteration, it would be something like the maturation. And so the structures can just re fold back to their original shape or their original arrangement as long as that primary structure, which is that most important structure stays intact because if the primary structure sustained any kind of damage, it would severely affect the entire protein. So, answer Choice A. Is the correct answer. I hope you found this video to be helpful. Thank you and goodbye
