Question

Some proteins are composed of two or more polypeptides. Suppose the DNA template strand sequence 3′-TACGTAGGCTAACGGAGTAAGCTAACT-5′ produces a polypeptide that joins in pairs to form a functional protein.

What term is used to identify a functional protein like this one formed when two identical polypeptides join together?

Accepted Answer

Hey, everyone. Let's take a look at this question together which of the following statements is true regarding functional proteins. Is it answer choice A they are formed from the interaction of two or more polypeptides. Answer choice B they are more sensitive to temperature N P H answer choice C they are globular in shape or answer choice D. All of the above statements are correct. Let's work this problem out together to try to figure out which of the following statements regarding functional proteins is true. So let's recall some information that we have learned about functional proteins, including some of their key defining characteristics in order to determine which of the following statements is true. So we have our functional proteins, which we know some things about them are that they have a specific biological function are formed from the interaction between two or more polypep tis, which is essential for the proteins function. They are more sensitive to temperature and ph H changes. Since those can alter the protein's shape and affect its ability to carry out the function. Since changes in temperature or P H can alter the shape and affect the ability to carry out the function and they have a globular shape, meaning that they are spherical, which is important or their function since the shape allows them to interact with other molecules in a specific way. And so now that we know this about those functional proteins, let's try to determine which of the following statements is true. Well, answer choice A says that they are formed from the interaction of two or more polypeptides, which we know that they are formed from that interaction between two or more polypeptides. So answer choice A is a true statement. Answer choice B because they are more sensitive to temperature and P H which we know that they are sensitive to those temperature and P H changes since it can alter the protein's shape and can also result in protein denaturation. So answer choice B is also a true statement. And answer choice C says that they are globular in shape which we know is also true since they do have that globular shape, meaning that rough spherical shape. So answer choices A B and C are all true statements regarding functional proteins, which means that answer choice D, all of the above statements are correct is the correct answer. Since we know that answer choice A B and C are all true statements regarding functional proteins. Since they are formed from that interaction between two or more polypeptides, they are more sensitive to temperature and P H and they are also globular in shape. So answer choice. D all of the above statements are correct is the best answer. I hope you found this video to be helpful. Thank you and goodbye.
