Binary fission in bacteria..... Please tell
Answers
Answer:
Explanation:
→ In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Many prokaryotic organisms such as bacteria reproduce by the process of binary fission.
Binary Fission of a bacterial cell involves mainly three steps:
Replication of DNA
The bacterial chromosomes divides in formation of two circular chromosomes At one stage, dividing bacteria appear like Greek letter theta.
Mesosome division
The parent chromosome is attached to a mesosome. It begins to divide because of synthesis of membrane between DNA - Mesosome attached sites.
As a result, each Mesosome is pushed in the daughter cells.
Cross wall formation
A peripheral ring in cell membrane invaginates and continues to grow until 2 cells get separated. The two events septum and cross wall synthesis take place simultaneously.
