tRNA is attached to specific proteins in the cell’s cytoplasm.

Answer 1

The true statement among the options provided is:

The human body uses 20 amino acids to form all types of proteins.

This statement is accurate as all proteins are made from combinations of these 20 standard amino acids.

The other statements are incorrect. Amino acids must be assembled in a specific order to create functional proteins. Additionally, amino acids form polypeptide chains via peptide bonds between the amino group of one amino acid and the carboxyl group of another, not through carbon-carbon bonds. Lastly, tRNA (transfer RNA) is not attached to proteins; it is actually attached to specific amino acids and acts as an adapter in the translation of mRNA into proteins.
