The Three Domains Flashcards

All 4 cards in this deck

Name the three domains in the three-domain classification system.

Archaea, Bacteria and Eukarya.

Give one reason why the three-domain classification system was proposed instead of the five kingdoms.

Genetic analysis (comparing DNA/RNA) showed the DNA of archaea is more similar to that of eukaryotes than to bacteria.

Which kingdom did Carl Woese's genetic analysis split into two separate domains?

The prokaryotes, which he split into Archaea and Bacteria because their genetic sequences are very different.

Which types of organism are in the domain Eukarya?

Animals, plants, fungi and protists (all organisms whose cells have a nucleus).
