Responses
Their structure is related to their function.
They carry oxygen in human blood.
They are created by mutations in DNA.
Their main function is to cause mutations.
A) Their structure is related to their function.

The correct statement is: "Their structure is related to their function."
To determine the answer, we need to understand the basics of proteins. Proteins are large, complex molecules composed of chains of amino acids. They play a crucial role in the functioning of cells and serve various functions in the body.
To determine which statement is true, we need to evaluate each option:
1. "Their structure is related to their function." This is true because the structure of a protein is directly linked to its function. The specific arrangement of amino acids determines the protein's shape and its ability to interact with other molecules, which ultimately dictates its function.
2. "They carry oxygen in human blood." This statement is not true for all proteins. While some proteins, such as hemoglobin, carry oxygen in the blood, there are many other types of proteins that have different functions unrelated to oxygen transport.
3. "They are created by mutations in DNA." While DNA mutations can lead to changes in protein structure and function, not all proteins are created through mutations. Proteins are initially synthesized based on the genetic information encoded in the DNA and undergo various modifications to form functional proteins.
4. "Their main function is to cause mutations." This statement is incorrect. Proteins have numerous functions in the body, including catalyzing chemical reactions, transporting molecules, providing structural support, and acting as signaling molecules. Causing mutations is not a primary function of proteins.
By evaluating each option and considering our understanding of proteins, we can conclude that the correct answer is "Their structure is related to their function."
