A) the ancient convergence of two cell types (i.e., prokaryotes and eukaryotes).
B) that prokaryotes and eukaryotes evolved from a common ancestral cell.
C) that bacteria share a common ancestor with archaea but not with eukarya.
D) that prokaryotes are cells with a nucleus.
E) that the genome of Haemophilus influenzae has about 2 billion base pairs.

Question

Quizplus · Accepted Answer

Analysis of DNA sequences has provided evidence that prokaryotes and eukaryotes evolved from a common ancestor cell. This is supported by similarities in genetic code, protein synthesis, and biochemistry between these groups, as well as by the presence of shared genetic material in their genomes. This idea is commonly known as the endosymbiotic theory.
