Question

what is the primary role of ribosomes in both prokaryotic and eukaryotic cells?
a. storing dna
b. controlling cell division
c. synthesizing proteins
d. providing structural support

Explanation:

Ribosomes are cellular structures. In both prokaryotic and eukaryotic cells, their main function is related to protein - related processes.

• Option a: Storing DNA is mainly the function of the nucleus (in eukaryotes) or the nucleoid region (in prokaryotes), not ribosomes.
• Option b: Controlling cell division is a complex process involving multiple genes and regulatory mechanisms, not the role of ribosomes.
• Option c: Ribosomes are the sites of protein synthesis. They read the mRNA sequence and assemble amino acids into polypeptide chains (proteins) according to the genetic code.
• Option d: Providing structural support is more related to the cytoskeleton in cells, not ribosomes.

Answer:

C. Synthesizing proteins
