Solution:
Ribosomes are, called as protein factories. Each ribosome has two unequal parts, small and large. The larger subunit of ribosome has a groove for pushing out the newly formed polypeptide and protecting the same from cellular enzymes. The smaller subunit fits over the larger one like a cap but leaves a tunnel for mRNA. The two subunits come together only at the time of protein formation.
