During prophase of mitosis, which of the following events occurs?
A
Chromatin condenses into visible chromosomes and the mitotic spindle begins to form.
B
The nuclear envelope fully re-forms around each set of chromosomes and chromosomes decondense.
C
Sister chromatids separate and move toward opposite poles of the cell.
D
Sister chromatids align at the cell equator (metaphase plate).
Verified step by step guidance1
Understand the stages of mitosis: prophase, metaphase, anaphase, and telophase, each characterized by specific cellular events.
Recall that during prophase, chromatin (the loosely packed DNA) begins to condense into visible chromosomes, making them easier to separate later.
Recognize that the mitotic spindle, a structure made of microtubules, starts to form during prophase to help segregate chromosomes.
Note that the nuclear envelope does not fully re-form during prophase; instead, it breaks down later to allow spindle fibers to interact with chromosomes.
Identify that sister chromatids separate during anaphase and align at the metaphase plate during metaphase, not prophase.
