In binary fission, DNA from the parent cell _________ before it produces daughter cells.
In binary fission, DNA from the parent cell replicates before it produces daughter cells.
In binary fission, DNA from the parent cell replicates before it produces daughter cells.
In binary fission, DNA from the parent cell replicates before it produces daughter cells.
To understand how this process works, let me explain binary fission in more detail. Binary fission is a form of asexual reproduction that occurs in prokaryotic organisms, such as bacteria. It involves the division of a single parent cell into two genetically identical daughter cells.
Here's how the DNA replication happens in binary fission:
1. The parent cell elongates: The parent cell elongates and duplicates its cellular components, including its DNA.
2. DNA replication begins: The process starts with the replication of the circular DNA molecule present in the parent cell. This replication begins at a specific origin site on the DNA.
3. DNA replication continues: Enzymes called DNA polymerases move along the DNA molecule and synthesize new strands that are complementary to the original strands. This process proceeds in both directions from the origin site until the entire DNA molecule is replicated.
4. Daughter DNA molecules form: As the DNA replication progresses, the parent cell elongates further, and the two new daughter DNA molecules move away from each other. Each daughter DNA molecule is an exact copy of the original DNA molecule.
5. Septum formation: A cell membrane begins to grow inward at the center, eventually dividing the parent cell into two daughter cells.
6. Completion of binary fission: Once the septum has completely formed, the two daughter cells pinch off from each other, resulting in two independent and genetically identical cells.
So, to answer your question, DNA from the parent cell replicates before it produces daughter cells through binary fission.
