Eukaryotic Cell. Transcription and translation are spatially and temporally separated in eukaryotic cells; that is, transcription occurs in the nucleus to produce a pre-mRNA molecule. The pre-mRNA is typically processed to produce the mature mRNA, which exits the nucleus and is translated in the cytoplasm.
Mitosis occurs only in eukaryotic cells and the process varies in different organisms. For example, animals undergo an open mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi undergo a closed mitosis, where chromosomes divide within an intact cell nucleus.he process of mitosis is divided into stages corresponding to the completion of one set of activities and the start of the next.
