Which of following statements are true? Proteins are readily used by the body for energy. Proteins are made from amino acids. Proteins contain the code for building DNA. DNA contains the code for building proteins.

Proteins are made from amino acids.

DNA contains the code for building proteins.

Explanation:

"Proteins" are made of small organic molecules called "amino acids." These are its building blocks and it helps make the protein in its linear chains.

Proteins are not readily used by the body for energy, instead the body readily uses carbohydrates for energy.

Proteins do not contain the code for building DNA, rather, the DNA contains the code for building proteins. These codes are like DNA instructions which are converted into an "RNA message." This message is then translated in order to produce protein.
