प्रश्न
Between a prokaryote and a eukaryote, which cell has a shorter cell division time?
Advertisements
उत्तर
Prokaryotic cells have shorter cell division times than eukaryotic cells. A typical eukaryotic cell cycle is illustrated by human cells in culture. These cells divide once approximately every 24 hours. In bacteria (E.coli) cell cycle is of 20 minutes.
