Question

IS THIS RIGHT??? (medal+fan)
Until recently, the Archaea were classified with Bacteria in the Kingdom Fonera. They have now been separated into their own domains, yet they do share some similarities with Bacteria. In which of the following ways are the Archaea similar to Bacteria?

They both lack a membrane-bound nucleus. < this one?
They both can survive in extreme environments.
They have the same types of cell membranes.
They replicate their DNA the same way.

Answer 1

@lexber Yes.

Answer 2

Ok so why do you think this? Can you eliminate why it isn't the other choices?

Answer 3

Archaea cell membrane consists of Ether-linked lipids and pseudopeptidoglycan.
Bacteria cell membrane consists of Ester- linked lipids and peptidoglycan

Answer 4

Internal Cell Structure:
Archaea No membrane bound organelles
Bacteria No membrane bound organelles

Answer 5

Gene Structure:
Archaea circular chromosomes
Bacteria circular chromosomes but difference is that the bacteria have a unique translation and transcription different from that of Archaea.

Answer 6

Now the metabolism methanogenisis can only be Archaea.
However Bacteria on the other hand has many like photosynthesis, aerobic and anaerobic respiration, fermentation, and autotrophy.

Answer 7

Reproduction is exactly the same both asexually with horizontal gene transfer.

Answer 8

Keep in mind that the asexual reproduction in all bacteria (Eubacteria and Archeae) is not mitosis, but binary fission. Result is the same, two daughter cells that each of one of the two strands from the mother cell and are identical (assuming 100% copy without errors, aka mutations).

Answer 9

Yes @mrdoldum I believe I said that if not I had meant to.
