Question

Which of the following is true about protein molecules?
A.
The shape and folded structure of a protein molecule are important in determining its function.
B.
Protein molecules are made up of strands of DNA joined together by amino acid sequences.
C.
The sequence of amino acids that make up a protein molecule do not affect its function.
D.
Protein molecules have many functions in the body, including the storage of genetic information.

Answer 1

The correct answer is option A- The shape and folded structure of a protein molecule are important in determining its function.

Justification: Let's take an example of sickle cell anemia in which the structure of hemoglobin changes due to a change in one amino acid. A small change in amino acid will change the bonds which will affect the structure and folding of the protein. A single change of amino acid can results in the change of protein’s function and structure.

Answer 2

Answer:

A. The shape and folded structure of a protein molecule are important in determining its function.

Explanation:

Proteins are organism compounds that participate in countless biological processes in living organisms, in addition to being able to generate tissues and organs essential for the survival of a living being (however, the protein is not responsible for the storage of genetic information).

Proteins are made up of amino acids, and in order for their function to be performed, they need to assume a specific shape through a folded structure. That is, the shape and folded structure of a protein molecule are important in determining its function.
