Question

what is the clinical application of knowing that bacterial ribosomes are 70s while human ribosomes are 80s ?

Answer 1

The purpose of the ribosome is to translate messenger RNA (mRNA) into proteins with the aid of tRNA.

All prokaryotes have $80s$ ribosomes , (where S=Svedberg units) ribosomes while eukaryotes contain larger ribosomes in their cytosol. The $70s$ ribosome is made up of a and subunits. The $50$ S subunit contains the S and S rRNA while the $30$ S subunit contains the 16S rRNA. These rRNA molecules differ in size in eukaryotes and are complexed with a large number of ribosomal proteins, the number and type of which can vary slightly between organisms. The ribosome is the most commonly observed intracellular multiprotein complex in bacteria.
