WebMar 31, 2024 · Cycloheximide inhibits the elongation step of protein synthesis. Polysomes accumulate in inhibited cells because ribosomes do not terminate normally and new ribosomes enter the polysome, eventually saturating the mRNA. Pactamycin inhibits initiation, and consequently polysomes break down in the presence of this drug. WebApr 9, 2024 · Ribosomes function as a workbench for protein synthesis, that is, they receive and translate genetic instructions for the formation of specific proteins. During protein synthesis, mRNA attaches to the 30s subunit and amino acid-carrying transfer RNAs (tRNA) attach to the 50s subunit (Figure 2.4 D. 1 ).
