Multiple Choice
During prophase of mitosis, which of the following events occurs?
A
Chromatin condenses into visible chromosomes and the mitotic spindle begins to form as centrosomes move apart.
B
Sister chromatids align along the metaphase plate.
C
Nuclear envelopes re-form around two sets of chromosomes and chromosomes decondense.
D
Sister chromatids separate and move toward opposite poles of the cell.
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 uncondensed form of DNA) begins to condense into visible chromosomes, making them distinguishable under a microscope.
Recognize that the mitotic spindle, a structure made of microtubules, starts to form during prophase, originating from centrosomes that begin to move apart to opposite poles of the cell.
Note that sister chromatids aligning along the metaphase plate occurs during metaphase, not prophase.
Remember that nuclear envelope re-formation and chromosome decondensation happen during telophase, while sister chromatids separating and moving to opposite poles occur during anaphase.
