Question

use your class notes and 6.2 textbook link to answer the following.
question 10 2 pts
cytokinesis occurs
immediately after the chromosomes make exact copies of themselves.
as mitosis ends.
immediately after the spindle fibers are formed.
when osmotic pressure is too low.

Explanation:

To solve this, we analyze each option:

1. Chromosome replication (DNA replication) occurs in interphase, not immediately before cytokinesis. So the first option is wrong.
2. Cytokinesis is the division of the cytoplasm, which happens at the end of mitosis (or meiosis), dividing the cell into two daughter cells. This matches the process.
3. Spindle fibers form during prophase of mitosis, and cytokinesis is much later, so this option is incorrect.
4. Osmotic pressure is not related to the timing of cytokinesis, so this is irrelevant.

Answer:

B. as mitosis ends.
