Question

Quizplus · Accepted Answer

Evidence from ribosome contents and DNA content in the nucleus supports the hypothesis that eukaryotes are derived from bacteria. Eukaryotic ribosomes are similar in size and composition to those of bacteria, while their DNA content indicates a potential origin from an endosymbiotic event in which a bacterium was engulfed by a larger host cell. These bacterial features in eukaryotes suggest a common ancestry and support the idea of an evolutionary link. Antibiotic resistance does not necessarily provide evidence of evolutionary relatedness between bacteria and eukaryotes.
