During prophase, a stage in the cell cycle,

Question

a
the nuclear envelope breaks down and chromatin condenses into chromosomes.
b
the chromosomes in the cell begin to move and align at the equator of the cell.
c
the cell begins to separate into two new genetically unique cells.
d
the cell duplicates its genetic material- doubling the number of chromossomes.

Answer 1

The correct answer is:

a the nuclear envelope breaks down and chromatin condenses into chromosomes.

During prophase, which is the first stage of mitosis, the chromatin condenses into distinct chromosomes, and the nuclear envelope begins to break down, preparing for the subsequent stages of cell division. Options b, c, and d describe events that occur in later stages of mitosis, not during prophase.
