Which domain of life shares the most recent common ancestor with eukaryotic nuclear rRNA genes?
Bacteria
Archaea
Mitochondria
Viruses
Based on rRNA phylogeny, mitochondrial rRNA genes share the closest evolutionary relationship with which of the following?
Eukaryotic nuclear rRNA genes
Archaeal rRNA genes
Bacterial rRNA genes
Chloroplast rRNA genes
Which endosymbiotic event occurred first in the evolution of eukaryotes, and what evidence supports this?
Mitochondrial endosymbiosis; all eukaryotes have mitochondria or mitochondrial remnants
Chloroplast endosymbiosis; plants and algae depend on photosynthesis
Both events occurred simultaneously; eukaryotic cells needed both organelles at the same time
Chloroplast endosymbiosis; chloroplasts provide energy, which allowed mitochondria to evolve
Which of the following provides evidence that mitochondria originated through endosymbiosis?
Mitochondria have their own DNA, similar to bacterial genomes
Mitochondria are surrounded by a single membrane, like the nucleus
Mitochondria divide by binary fission, like bacteria
Mitochondria can survive independently outside of eukaryotic cells
Which kingdom shares the most recent common ancestor with Animals?
Plants
Fungi
Protists
Bacteria
