Document Summary
Ba(cid:272)teria & ar(cid:272)hae are (cid:271)oth prokar(cid:455)otes (cid:271)e(cid:272)ause the(cid:455) do(cid:374)"t ha(cid:448)e a u(cid:272)leus. A lot of archae have similar processes to eukaryotes. Archae is very close to eukaryotes, closer to it than bacteria. In some ways, archae resemble eukaryotic cells more than eubacteria. Some mechanisms of transcription & translation are different. The cell has a plasma membrane which is a selectively permeable filter. The dna can be in a nucleoid, which is a compact structure. A cell wall is a tough protective outer coat which is not in all prokaryotes. Flagellum is for locomotion, its not found on all prokaryotes. Eukaryotic cells have a cytoskeleton because they are much bigger. These cels have a nucleus and a nuclear membrane. Release of the biological info stored in the genome requires ge(cid:374)o(cid:373)e e(cid:454)pressio(cid:374). Viruses are(cid:374)"t (cid:272)lassified as being alive because they need cells to live, but they still have some genetic info, they do have genomes and most of it is rna.
