प्रश्न
List two essential roles of ribosome during translation.
State the function of ribosome as a catalyst in bacteria during the process of translation.
उत्तर
Two essential roles of the ribosome during translation are:
- They provide a surface for binding of mRNA in the groove of the smaller subunit of ribosomes.
- As a larger subunit of the ribosome has peptide transferase on its ‘P’ site, therefore, it helps in joining amino acids by forming peptide bonds.
