Document Summary
Prokaryotic cells do not have a nucleus whereas eukaryotic cells do have a nucleus: an example of a prokaryotic cell is bacteria. Does not consist of a nucleus but does have genetic material that floats in the cytoplasm (nucleoid). Contains a nucleus which has genetic material stored and a nuclear membrane outside. The dna is arranged in a spiral form (chromosome) floating in the cytoplasm. Transcription process takes place in the cytoplasm because it lacks a membrane-bound nuclei and other organelles. Translation and transcription are coupled so the process takes place when the mrna is being synthesized. Transcription process takes place in the nucleus, which the mrna is transported into the cytoplasm. Prokaryotes do not have a membrane bound chamber where genetic material is stored, or other organelles. Eukaryotes have a membrane bound chamber where dna is stored and other additional organelles. All prokaryotic cells have: cell wall - prevents the cell from bursting and gives bacteria its shape.
