MICROANATOMY

Detailed explanation-1: -Ribosomes contain two different subunits, both of which are required for translation. The small subunit (“40S” in eukaryotes) decodes the genetic message and the large subunit (“60S” in eukaryotes) catalyzes peptide bond formation.

Detailed explanation-2: -The eubacterial ribosome (70S), which plays a central role in protein synthesis, is composed of a small (30S) subunit and a large (50S) subunit. The small subunit is comprised of the 16S rRNA and more than 20 proteins, whereas the large subunit is comprised of the 23S and 5S rRNAs and more than 30 proteins (1, 2).

Detailed explanation-3: -The eukaryotic 80S ribosome is comprised of two unequal subunits that contain four different rRNAs and around 80 ribosomal proteins. Eukaryotic 40S subunit contains 18S rRNA and 33 proteins and the 60S subunit contains 25S, 5S, 5.8rRNA, and 47 ribosomal proteins.
