Polypeptide Chain

A long, continuous, and unbranched chain of amino acids linked by peptide bonds that forms part of the structure of proteins.

tRNA Molecules

Transfer RNA; small RNA molecules that transport amino acids to the ribosome during protein synthesis, ensuring the correct amino acid sequence is assembled according to the mRNA template.
