How many different proteins does the ribosome consist of ?
The correct option is Option 1) 80.
The ribosome is a complex molecular machine involved in protein synthesis. It is composed of two subunits, the large subunit and the small subunit, which come together during protein synthesis and dissociate afterward. These subunits consist of a combination of proteins and RNA molecules called ribosomal RNA (rRNA).
In eukaryotes, the ribosome consists of 80 different proteins in total. The large subunit contains approximately 50 different proteins, while the small subunit contains around 30 different proteins. These proteins play essential roles in various aspects of protein synthesis, including mRNA binding, tRNA binding, and catalyzing the formation of peptide bonds.
Therefore, Option 1) 80 is the correct answer for the number of different proteins that the ribosome consists of.
