Those giant white hair looking things. Each one is a **single cell** bacteria. It is the largest bacteria known to man with each cell growing up to 2mm. You can see them with the naked eye and they are even strong enough to be picked up.
They are also unique as they are the only bacteria where the dna has a nucleus like membrane around it.
No that is almost always the case. Life is filled with exceptions though, and this is one of them.
Mammals are supposed to give live births, but a platypus lays eggs.
"My skepticism about the authors' claim that the genome of 𝘛. 𝘮𝘢𝘨𝘯𝘪𝘧𝘪𝘤𝘢 is localized in membrane-bound compartments ─ which they call "pepins" ─ stems from the fact that their technically excellent EM images do not show a continuous membrane, at least not in one focal plane (Figure 4, F+G)."

Not my area of expertise, but you seem to know what your talking about. I'll give a read to the link if I remember tomorrow but I boosted because this is all very interesting.
@freemo I'm a fan of Jean-Marie Volland's and his colleagues work! however, this includes criticism of one of their claims. because this is science 😀
@STCmicrobeblog I would expect nothing less!
@freemo
I thought that was the difference between prokaryotes and eukaryotes, and there were single-celled organisms with a nucleus... Did I misunderstand something?
