Protein synthesis takes place on which cell structure?
Answer and explanation
Correct answer: A. Ribosomes
- Step 1: The translation of genetic instructions into functional polypeptides requires specialized non-membrane-bound ribonucleoprotein complexes.
- Step 2: Ribosomes serve as the physical cellular factories where transfer RNAs decode mRNA codons to assemble amino acid sequences into proteins.
- Step 3: In contrast, lysosomes conduct intracellular digestion, the Golgi apparatus modifies and packages proteins, and the nucleus houses genomic DNA.
Answer
Ribosomes.
Why not the others: Vacuoles are membrane-bound storage organelles that maintain cell turgor and sequester waste; Lysosomes degrade macromolecules using hydrolytic enzymes; Centrioles organize the mitotic spindle during animal cell division.
