Which statement is true of all proteins? Their structure is related to their function, they carry oxygen in a human blood, their main function is to cause mutations, They are created by mutations in DNA
The statement "Their structure is related to their function" is true of all proteins. A protein's structure, which is determined by the sequence of amino acids it is made up of, is specifically designed to carry out its particular function in the body. The other statements are not true of all proteins. Some proteins, such as hemoglobin, carry oxygen in human blood, but this is not a universal function of all proteins. Proteins do not have the main function of causing mutations; mutations can occur in DNA, which can then affect the resulting protein. Additionally, while mutations can contribute to the creation of genetic variation and potentially give rise to new proteins, proteins themselves are not directly created by mutations in DNA.
