What is the process of endospore formation in bacteria?
What is the process of endospore formation in bacteria?
- The DNA replicates and the new DNA moves to one end of the cell (correct)
- The original cell bursts, releasing the endospore
- A thick, resistant wall then surrounds the new DNA
- The contents of the endospore shrink as water is removed and its metabolism stops
