Human → Kangaroo → Lizard → Frog → Salmon

What are the three domains of life?

Bacteria, Archaea, Eukarya

What do Eukarya and Archaea have in common?

No peptidoglycan in cell walls, same response to penicillin, use RNA polymerase

What do Bacteria and Archaea have in common?

No membrane-bound organelles and circular DNA

Which domain has a nuclear envelope?

Only Eukarya

Which domain has membrane-bound organelles?

Only Eukarya

Which domain has peptidoglycan in cell walls?

Only Bacteria

Which domains have RNA polymerase?

All three, but Archaea and Eukarya have several kinds, Bacteria has one kind

Which domains use methionine as the first amino acid in protein synthesis?

Archaea and Eukarya

Which domains have introns in genes?

Eukarya and some Archaea

How do the domains respond to antibiotics like streptomycin and chloramphenicol?

Bacteria – growth inhibited; Archaea & Eukarya – not inhibited

Which domains have circular chromosomes?

Bacteria and Archaea

Which domains can grow at temperatures >100°C?

Some Archaea

How do you identify plant groups using a dichotomous key?

1. a. Vascular tissue → Go to 2; b. No vascular tissue → Bryophyta; 2. a. Seeds → Go to 3; b. No seeds → Filicinophyta; 3. a. No flowers → Coniferophyta; b. Flowers → Angiospermophyta

Which plant has no vascular tissue?

Bryophyta

Genus = Homo, Species = sapiens

What does a cladogram show?

Divergent evolution of organisms

What is a clade?
