Amino acids do not need to be assembled in a particular order.

Amino acids form a polypeptide chain via carbon-carbon bonds.
Amino acids form a polypeptide chain via carbon-carbon bonds.

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

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

Answer 1

The true statement among the options provided is:

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

The other statements are incorrect for the following reasons:

1. Amino acids do need to be assembled in a particular order to form functional proteins, as the sequence determines the protein's structure and function.

2. Amino acids form a polypeptide chain via peptide bonds, not carbon-carbon bonds. Peptide bonds link the amino group of one amino acid to the carboxyl group of another.

3. tRNA (transfer RNA) is not attached to specific proteins; instead, it carries specific amino acids to the ribosome during protein synthesis based on the codon sequence of mRNA.
