Question

Both bacteria and archaea have cell membranes which contain a hydrophobic portion. In the case of

bacteria, it is a fatty acid; in the case of archaea, it is a hydrocarbon (phytanyl). Both of them posses a cell

wall. In bacteria, it is made up of peptidoglycan, whereas archaea cell wall contains pseudomurein.

Bacterial and archaeal flagella also differ in their chemical structure.

A scientist has isolated a new species of prokaryote. He identified that the specimen is rod shaped. He

analysed its chemical composition and found fatty acids, N-acetyl glucosamine, N-acetyl muramic acid

and teichoic acid as the constitutent. It has circular chromosome with a single origin of replication. Is the

specimen most likely an Archaea, a Gram-positive bacterium, or a Gram-negative bacterium? How do you

know?​
