Archaea

Question 1

What are some similarities between archaea and bacteria?

Answer 1

Circular DNA, plasmids, no nucleus, 70s ribosomes, have inclusions

Question 2

How do plasma membranes differ between archaea and bacteria?

Answer 2

Bacteria = phospholipids containing ester linkages plus hopanoids and bactoproral
Bilayer

Archaea = ether-linked glycolipids containing phytaryl
Monolayer or bilayer

Question 3

How do cell walls differ between archaea and bacteria?

Answer 3

Bacteria = virtually all contain peptidoglycan
Some contain S-layers

Archaea = no peptidoglycan
Virtually all contain S-layers

Question 4

How do motility structures differ between archaea and bacteria?

Answer 4

Bacteria = pili, flagella, focal adhesions

Archaea = hami, archaellum

Question 5

Would archaea be affected by antibiotics targeting bacterial ribosomes?

Answer 5

Yes because both archaea and bacteria have 70s ribosomes

Question 6

Would archaea be affected by antibiotics targeting bacterial cell walls?

Answer 6

No because their cell walls are comprised of different things

Question 7

What type of motility do archaea have?

Answer 7

They would likely have swarming motility because they are peritrichous
