List two essential roles of ribosome during translation.

(N/A) The important functions of ribosome during translation are as follows:
$1$. Ribosome acts as the site where protein synthesis takes place from individual amino acids. It consists of two subunits. The smaller subunit comes in contact with $mRNA$ and forms a protein-synthesizing complex,whereas the larger subunit provides binding sites for $tRNA$ and amino acids.
$2$. Ribosome acts as a catalyst for the formation of peptide bonds. For example,the $23S$ $rRNA$ in bacteria acts as a ribozyme to catalyze peptide bond formation.
