Protein synthesis depends on ribosomes, which are vital biological components. A polypeptide chain is created by joining together amino acids, which is done by the big and tiny subunits of the ribosome, which work together to read the genetic information in mRNA.

The ribosome's large component catalyzes the creation of peptide bonds between neighboring amino acids to create the polypeptide chain, while the tiny subunit is in charge of identifying and attaching to the mRNA molecule. The ribosome moves along the mRNA molecule in a step-by-step manner during this process, joining amino acids together one at a time until a whole polypeptide chain is created. A functional protein can be created once the polypeptide chain is finished by folding into the correct three-dimensional structure.

The two ribosomal subunits cooperate to properly and effectively convert the genetic information in mRNA into functional proteins, making the ribosome an essential part of the protein synthesis machinery in all living cells.

The correct option is 1.
