During prophase, a stage in the cell cycle,

Question

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

Answer 1

The correct answer is:

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

During prophase, which is the first stage of mitosis, the chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The other options describe processes that occur at different stages of the cell cycle.
