In binary fission, DNA from the parent cell _________ before it produces daughter cells.(1 point
coils up
produce cyctoplasm
moves toward one pole
replicates
replicates
To determine the answer to this question, we need to understand what happens during binary fission. Binary fission is a form of asexual reproduction in which a single parent cell divides into two identical daughter cells. This process is commonly observed in prokaryotic organisms such as bacteria.
Now, let's look at each of the options given:
1. Coils up: During binary fission, the DNA in the parent cell does not necessarily "coil up" in a specific way, so this option is unlikely to be the correct answer.
2. Produces cytoplasm: While the production of cytoplasm is essential for cell division, it does not specifically relate to the DNA in the parent cell. Therefore, this option is also unlikely to be the correct answer.
3. Moves towards one pole: This option refers to the movement of the DNA as it separates into two parts. During binary fission, the DNA does indeed move towards opposite poles of the parent cell. This movement facilitates the subsequent division into two daughter cells, making this option a possible correct answer.
4. Replicates: DNA replication is a crucial step in binary fission. To produce two identical daughter cells, the parent cell's DNA must first replicate. Therefore, this option is also a possible correct answer.
Based on the explanations above, the options "Moves towards one pole" and "Replicates" are both valid answers for your question.
