Question

Molecular Expressions Photo Gallery: Mitosis

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

Answer 1

During prophase, the correct statement is:

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

During prophase, the chromatin condenses into distinct chromosomes, and the nuclear envelope begins to break down as the cell prepares for mitosis. The other options describe processes that occur at different stages of the cell cycle.
