Multiple Choice
Which of the following is a similarity shared by both prokaryotic and eukaryotic cells?
A
Both have their DNA arranged in linear chromosomes.
B
Both have a nucleus that contains their genetic material.
C
Both possess membrane-bound organelles such as mitochondria.
D
Both contain ribosomes for protein synthesis.
Verified step by step guidance
1
Understand the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have both.
Review the structure and function of ribosomes. Ribosomes are responsible for protein synthesis and are found in both prokaryotic and eukaryotic cells, although their size and structure may differ slightly.
Eliminate incorrect options based on cell characteristics: Prokaryotic cells do not have linear chromosomes (their DNA is circular), a nucleus, or membrane-bound organelles like mitochondria.
Focus on the correct option: Ribosomes are a universal feature shared by both prokaryotic and eukaryotic cells, as they are essential for translating mRNA into proteins.
Conclude that the correct answer is: 'Both contain ribosomes for protein synthesis,' as this is the similarity shared by both cell types.
