Final answer:
Ribosomes are responsible for protein synthesis, linking amino acids together into chains forming complex protein molecules. The statement is true.
Step-by-step explanation:
Ribosomes are the cellular structures responsible for protein synthesis. They are large complexes of protein and rRNA, consisting of a large and a small subunit. Ribosomes bind to mRNA and translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.
Therefore, these tiny bodies are indeed the sites of protein synthesis, where amino acids are linked together into chains that eventually form large, complex protein molecules.
