Question

platinum - based drugs are very effective at treating cancer, but they are also very toxic to non - cancerous cells as well. a recent study showed that platinum - based drugs affected the structure of the nucleus. specifically, a region within the nucleus known as the nucleolus was damaged by these drugs. this is noteworthy because the nucleolus is the area where the parts of ribosomes are made. what process would be directly disrupted by the failure to make ribosomes?

○ lipid synthesis
○ cellular respiration
○ protein synthesis
○ photosynthesis

Explanation:

Ribosomes are the sites of protein synthesis. Without functional ribosomes, the process of assembling amino - acids into proteins cannot occur. Lipid synthesis occurs in the endoplasmic reticulum, cellular respiration occurs in mitochondria, and photosynthesis occurs in chloroplasts in plant cells.

Answer:

C. protein synthesis
