Fisi (biologi)

Dari Wikipedia bahasa Indonesia, ensiklopedia bebas
Pembelahan biner pada prokariota
1. The bacterium before binary fission is when the DNA is tightly coiled.
2. The DNA of the bacterium has uncoiled and replicated.
3. The DNA is pulled to the separate poles of the bacterium as it increases size to prepare for splitting.
4. The growth of a new cell wall begins to separate the bacterium.
5. The new cell wall fully develops, resulting in the complete split of the bacterium.
6. The new daughter cells have tightly coiled DNA rods, ribosomes, and plasmids; these are brand new organisms.

Dalam biologi, fisi adalah pembelahan dari sel (atau tubuh, populasi, atau spesies) menjadi dua atau lebih bagian dan regenerasi dari bagian tersebut menjadi sel yang terpisah (tubuh, populasi, or spesies).[1][2][3] Pembelahan biner menghasilkan dua sel, populasi, spesies, dll. yang terpisah, sementara fisi multipel menghasilkan lebih dari dua sel, populasi, spesies, dll.
