Answer 1

The true statement is: "The human body uses 20 amino acids to form all types of proteins."

Brief explanation: Protein function depends on the specific sequence of amino acids (so order matters). tRNAs are charged with specific amino acids (not proteins). Amino acids are linked by peptide (amide) bonds between the amino and carboxyl groups, not carbon–carbon bonds.
