Which would most likely be used by ribosomes to complete protein synthesis?

Ribosomes primarily use messenger RNA (mRNA) as a template to guide protein synthesis. Transfer RNA (tRNA) plays a crucial role by bringing the appropriate amino acids to the ribosome, where they are added to the growing polypeptide chain. Additionally, ribosomal RNA (rRNA) is a structural component of ribosomes, facilitating the translation process. Together, these components enable the synthesis of proteins from amino acids.
