Task 01
1.1 How Archaea is similar to Eukaryotes and how they differ from Bacteria.
Once classified as bacteria in the domain prokaryotes that is until the analysis of archaea DNA showed that they are very much different from bacteria (Waggoner & Speer, 1994, para.1-2). Archaea are now known to have a different evolutionary history and may even be the closest living relatives to the first organisms on earth (Noel, n.d, para.3). Archaea are extremophiles meaning that they can exist under some of the harshest and most extreme conditions ranging from rift vents in deep sea with temperature over 100 degrees centigrade to extremely acidic or alkaline lakes to digestive track of animals (Waggoner & Speer, 1994, para.4). There are three main divisions of archaea the Crenarchaeota, Euryarchaeota and Koracrchaeota.

Archaea may not have same physical similarities to eukaryotes but their metabolic pathways and genes are. Archaea’s similarities to eukaryotes can be seen in the metabolic pathway like the transcription and translation process. Protein synthesis in both begins with amino acid methionine as well as both
