During prophase, a stage in the cell cycle,

Question

a
the cell duplicates its genetic material.
b
the chromosomes in the cell begin to move.
c
the nuclear envelope breaks down.
d
the cell begins to separate into two new cells.

Answer 1

During prophase, the correct statement is:

c) the nuclear envelope breaks down.

Prophase is the first stage of mitosis, where the chromosomes condense and become visible, and the nuclear envelope begins to disintegrate, facilitating the separation of genetic material.

• Option a) occurs during the S phase of interphase, where DNA replication takes place before mitosis.
• Option b) refers to the movement of chromosomes, which primarily happens during metaphase and anaphase.
• Option d) refers to cytokinesis, which occurs after mitosis is complete.
