What Is Binary Fission?
In binary fission, the DNA of the cell replicates. Each copy of the DNA
Hi, I'm Jim Shields for About.com, and today I'm going to teach you about binary fission. Prokaryotic cells, like bacteria, also need to reproduce. But unlike eukaryotic cells, they don't use mitosis. Because they lack a nucleus, they can use a simpler replication process known as binary fission. In binary fission, the DNA of the cell replicates, and each copy of the DNA attaches to the cell membrane. Once this duplication is complete, the cell elongates and the membrane closes between the two DNA copies to create two identical daughter cells. This simpler process can be up to 10 times faster than mitosis, which is how eukaryotic cells reproduce. Thanks for watching. To learn more about biology, visit us on the web at About.com.
