The true statement is:
**The human body uses 20 amino acids to form all types of proteins.**
The other statements are incorrect:
- Amino acids **must** be assembled in a specific order to form functional proteins, as the sequence determines the protein's structure and function.
- tRNA is not attached to proteins; rather, it carries amino acids to the ribosome for protein synthesis, where it has an anticodon that pairs with mRNA.
- Amino acids form a polypeptide chain via **peptide bonds**, not carbon-carbon bonds.
