Prokaryote structure (article) | Khan Academy
Key points: Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.

Prokaryote metabolism (article) | Khan Academy
Prokaryotes may perform aerobic (oxygen-requiring) or anaerobic (non-oxygen-based) metabolism, and some can switch between these modes. Some prokaryotes have special enzymes and pathways that let them metabolize nitrogen- or sulfur-containing compounds. Prokaryotes play key roles in the cycling of nutrients through ecosystems.

Can human mRNA be translated in vitro by prokaryotes? As the genetic code is universal, can mRNA from a human cell be correctly translated by a prokaryote in a in vitro translation system?
Short answer: Yes, you can. Usually these are coupled systems for transcription and translation. For these you clone the gene of interest into a vector which contains a prokaryotic promoter which is then used to generate the mRNA in the tube. This mRNA is then translated in the second step into a pr...

Shine-Dalgarno sequence and expressing proteins * Shine-Dalgarno sequence present in the prokaryotic mRNA plays a role in initiation of translation. In eukaryotes a Shine-Dalgarno like sequence is present but does not...
Eukaryotes have an analogous sequence called the Kozak sequence. cDNA is easily expressed in prokaryotes by substitution of the Kozak sequence for the Shine-Dalgarno sequence, using standard molecular biology techniques. A caveat is that not all eukaryotic protein will be properly expressed in bacte...

Do antigens protrude through the capsule/slime layer in prokaryotic organisms where these features are present? In prokaryotic organisms that have a slime layer or capsule, do intrinsic/extrinsic proteins and other mo...
They don't have to -- there are times in life of a bacteria (cell division, hunger, mutations, attacks of lysozyme and other enzymes, cell lysis) when any possible antigen gets less or more exposed. About escaping phagocitosis, there are numerous strategies to achieve it -- from forming a large slim...

What is the advantage of the way eukaryotes initiate translation? The eukaryote and prokaryote mechanism for translation is slightly different. Is there any advantage of the eukaryote translation mechanism ? Edit : I...
As far as I understand it (and I'll preface this by saying that initiation is **not** my strongest point), but prokaryotes utilize the beautiful **AGGAGG** Shine-Dalgarno sequence. Usually around 8bp upstream of the start codon, it is this sequence that the prokaryotic ribosome seeks out to initiate...
