Which Characteristics or Components are Distinctive of Eukaryotes

Question

Which characteristics or components are distinctive of eukaryotes?
A) Butylmethionine tRNA
B) Cell division by fission
C) Presence of peptidoglycan
D) Membrane-enclosed nucleus
E) Ribosomes

Accepted Answer

The distinguishing feature of eukaryotes is that they have a membrane-bound nucleus, which separates the genetic material from the rest of the cell. The other choices are either found in other types of cells (butylmethionine tRNA in bacteria) or are not specific to eukaryotes (ribosomes are found in both eukaryotic and prokaryotic cells, for example).
