Therefore, you need to use genetic method (ribosomal RNA) to differentiate.Greeniehttps://www.blogger.com/profile/16723475560144858107noreply@blogger.comtag:blogger.com,1999:blog-36768584.post-66748214651259649572015-09-18T10:17:35.666-04:002015-09-18T10:17:35.666-04:00Moritz: Thanks for the helpful info!

Lipids in the cell wall are made of glycerol and fatty acids connected by ether linkages (vs. ester linkages in the other domains. Depending on the amount of chemistry they learned they should see that this is a huge difference)<br /><br />-Archaea have some properties they share with eukaryotes (Histones, Methionine as start of transcription, three types of RNA polymerase)<br /><br />Best, MoritzM.
