Life on Earth 005 - Archaea
In this video Paul Andersen describes the defining characteristics of members in the domain archaebacteria. He starts with a brief description of the phylogeny of this group. He then describes the major characteristics on an archaea, such as differences in the phospholipids. He explains how they reproduce through binary fission and finishes with a discussion of archaebacteria diversity.

Nice. I learned something from this short presentation. Microbiology has advanced greatly since the 1960's. Archaea weren't even on the 'map' back then. Thank you Dr. Anderson!

Bozeman Science with Paul Andersen are definitely my number 1 for science & biology information videos. Awesome!

@brianwitte2991 12 лет назад

When you compare proteins found in the Eukaryotic nucleus, they are more similar to proteins that perform similar functions in Archaea (not Archaebacteria). Cytosolic proteins in Eukarya, however, are most similar to bacterial proteins. It's an open question, though, whether this is evidence of endosymbiosis or the way genes assorted as the LUCA diversified into the three Domains.

Here, have my upvote. Thanks for explaining, did not understand why their membrane is so different.

@omarmohammadibrahim2197 8 лет назад

+yesthisiscat_ no one can answer why their membrane is different not even they. like, i cant say why i have two eyes. but we can only say what are the benefits they are getting. first, look carefully and you will see the fatty acids are ether likage, so its more inert than a ester bond. so the change very slowly if they do. secondly, they are so long that the can cover the whole periphery so give a better uniform structure. hope that helps :)

Hi Mr Anderson, can Archaea resist any microorganisms that causes disease eg virus? Their structures are so simple and hard to think a way to protect themselves.( extreme condition is a good protection anyway but some are not in extreme)Many thanks!

@HDfan13 11 лет назад

Very helpful, just like all of your videos. :) I'm just wondering how it came to be that bacteria and eucaryots have the same kind of phospholipids whereas archaea have different ones. Does that mean that LUCA had the bacteria/ eucaryot phospholipids and the other kind is an invention of the archaea exclusively?

@nevada8004 5 лет назад

Thanks for sharing sir

@s.sradon9782 7 лет назад

the A.T.P (energy) that the archaea produces must be a very inefficient process as the cell uses it's cytoplasm (jelly) t make it due to the lack of organelle called the mitochondria which results in a slower reproduction rate meaning that they might die out

@Roderlump02 7 лет назад

jakub rembacz you mean like every single procariot out there? Yeah sure they will die out soon

@Txfpf4all 11 лет назад

@brianwitte2991 12 лет назад

also - only some Methanogens are lithotrophs. Many methanogens (e.g. Methanosarcina spp) use acetic acid or methanol as substrates for methanogenesis.

@40ouncesofbeer 12 лет назад

Archaeal do contain cell wall. the cell wall contain pseudomurein, complex carbohydrates, or protein-glycoproteins if im correct

The gnome project? Is this a project run by gnomes or is it a project which has gnomes as its subject? I'm hoping it's the former, I'd like to think that, by night, my little gnome goes AWOL from his pond surveillance duties and hits the hot springs to study archaea in a pair of red speedos.

@BioZome313 12 лет назад

Nice attempt at describing a few characteristics of the archaea. A few corrections are in order. Archaea is a completely seperate branch from all other life forms. Archaea has no DNA. Strickly RNA. This is why they make exact copies of themselves. The term archaeobacteria was used from the 1950,s to the eary 1990,s. The gnome project confirmed the archaea have no DNA, no recognizable cell walls. Current list is 411 species. Dr Oppenheimer had discovered 24,000 species. and propagates them.

@malteeaser101 9 лет назад

'Eukaryote' or 'eukaryote'? 'Prokaryote' or 'procaryote'?

@JessMcNicholl 7 лет назад

Both are correct, but they came from the Greek word "karuon", so using a k is more common.

@WolfySnackrib666 10 лет назад

Let me teach you about Archaea Ottoia too! At 4,000 feet, the Ottoia are about as long as a pencil, with bodies about the size of a golf ball. But those at 20,000 feet have been found to eat full-grown sharks! At 30 or 40,000 feet... Well, you do the math.

Bacteria are a type of microbe. Archeaa are a type of microbe. That doesn't mean that bacteria are archeaa, or archeaa are bacteria.

They can have a peptidoglycan-like substance, cant think of the specifics right now though. Source 3rd year biochem major (lehinger textbook)

@saffron1006 8 лет назад

+nicofire0987 I thought the whole reason for the classification of archaea, is that they're prokaryotes that do not have peptidoglycan cells, any other bacteria that does would be in the domain eubacteria
