Which statements describe proteins? Select three options.Proteins are created from the code in DNA.Proteins are synthesized in the nucleus of a cell.DNA and RNA are proteins.Amino acids are the building blocks of proteins.Proteins affect the structures and functions of living things.The shape and the function of a protein are not related.

DNA contains instructions that are used to make proteins, so proteins are created from the code in DNA. Proteins are built from amino acids, and they help determine the structures and functions of living things. Protein shape is related to function, and proteins are synthesized by ribosomes rather than in the nucleus.
