Question #149084
what is the clinical application of knowing that bacterial ribosomes are 70s while human ribosomes are 80s ?
Expert's answer

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.
