B
Membrane-bound organelles
C
Linear DNA
D
Presence of a nucleus
Verified step by step guidance
1
Understand the basic definitions: Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope, while prokaryotes are unicellular organisms that lack a nucleus and membrane-bound organelles.
Identify the shared characteristics: Both eukaryotes and prokaryotes have ribosomes, which are essential for protein synthesis. Ribosomes are not membrane-bound and are present in both cell types.
Analyze the options: 'Ribosomes for protein synthesis' is a characteristic shared by both eukaryotes and prokaryotes. The other options, such as 'Membrane-bound organelles', 'Linear DNA', and 'Presence of a nucleus', are specific to eukaryotes.
Consider the structure of ribosomes: In both eukaryotes and prokaryotes, ribosomes are composed of ribosomal RNA (rRNA) and proteins, and they function as the site of translation in protein synthesis.
Conclude with the correct answer: The characteristic shared by both eukaryotes and prokaryotes is the presence of ribosomes for protein synthesis.
