Question

Prokaryotic cells and eukaryotic cells reproduce by mitotic cell division. Regardless of the type of cell, all cells must _____ before they divide.A) make a copy of their genetic informationB) separate sister chromatids from one anotherC) complete mitosisD) reconstruct their nucleus

Answer 1

Answer:

A

Explanation:

1. All cells, prokaryotic as well as eukaryotic cells divided into two daughter cells by mitotic division. Before division, every cell must replicate their DNA, and makes two copies of their DNA, and finally divide into two daughter cells with equal number of chromosome.

2. Each daughter cell contain equal number of chromosome and same as the parental cell in case of chromosome  number .

3. DNA replication occurs in the S phase( synthetic phase) of cell cycle.
