Core properties of living cells (identify the exception) Which of the following statements is NOT a universal property of all cells across the tree of life (including both prokaryotes and eukaryotes)?

Organelle with its own DNA, division, and partial autonomy Which cellular organelle typically contains its own DNA, divides within the cell, and exhibits a degree of genetic and metabolic autonomy?

Abilities of prokaryotes (identify the non-feature) Prokaryotic organisms exhibit many capabilities. Which of the following is NOT a typical feature of prokaryotes?

Exception to phospholipid bilayers among free-living organisms Most free-living organisms have phospholipid bilayer membranes. Which group is the notable exception because its membranes use chemically distinct lipids?

Carl Woese’s major taxonomic contribution Carl Woese and colleagues are best known for establishing which overarching classification framework based on ribosomal RNA comparisons?

Evidence for life in a newly discovered microscopic structure A newly observed microscopic structure is suspected to be living. Which observations would support the claim that it is a living organism?

Origin of the five-kingdom classification Who proposed the five-kingdom system that organized life into Monera, Protista, Fungi, Plantae, and Animalia?
