attempts left Check my work Select all that apply. Proteins vary widely in structure, whereas nucleic acids have rather uniform structures. How do you account for this major difference? Compared to proteins, which are made of up to 20 different amino acids, the composition of nucleic acids is considerably simpler. Proteins have many uses. Compared to nucleic acids, which are made up of many building blocks, the composition of proteins is considerably simpler. . Nucleic acids have many uses. A...
