In bacteria, binary fission can be modeled in two stages.
In bacteria, binary fission, the process of cell division, can be modeled in two stages:
1. Growth and Replication: The first stage involves the growth and replication of the bacterial cell. The cell elongates and replicates its genetic material (DNA) to form two identical copies.
2. Division: In the second stage, the cell membrane and cell wall constrict at the middle, forming a septum. This septum eventually separates the two copies of the genetic material, resulting in the formation of two identical daughter cells. Each daughter cell contains a complete set of genetic material and is capable of independent growth and replication.
To determine the correct answer, we can review the process of binary fission in bacteria.
Binary fission is a form of asexual reproduction that bacteria use to reproduce and increase their population. It involves a single cell dividing into two identical daughter cells.
The stages of binary fission can be summarized as follows:
1. Replication of DNA: The cell's DNA duplicates, creating two identical copies of the genetic material.
2. Elongation: The cell elongates in preparation for division, as the two copies of DNA move towards opposite ends of the cell.
3. Division: The parent cell membrane grows inward at the center, forming a new cell wall, which eventually separates the two daughter cells.
4. Cytokinesis: The cytoplasmic contents are evenly distributed between the two daughter cells, and each cell regains its normal shape.
Based on this, we can see that binary fission can be modeled in four stages - DNA replication, elongation, division, and cytokinesis.
Therefore, the correct answer to your question is "four stages."
