The antibiotic erythromycin binds specifically with the 50s portion of a ribosome. what effect do you expect this to have?

The antibiotic erythromycin binds specifically with the 50s portion of a ribosome and technically, only prokaryotes have a 50S ribosome (larger subunit of prokaryote’s 70s ribosome). So the process happens in prokaryotic organisms (mostly bacteria) and as we know, erythromycin is an antibiotic — performing a bactericidal activity which kills a bacteria or prokaryote.

Ribonuclease activity is a type of nuclease that catalyzes the degradation of rna into small components.

The answer is joseph is observing the colour of the reaction mixture to see whether proteins are present in the given solution.
