This is because each divided Cell needs it's own copy of the chromosomal DNA.

Chromosomes must replicate so that both cells that are formed from cell division can have the same genetic material.

DNA must replicate before cell division to make sure that each daughter cell is genetically identical.

Before cell division can take place, the cell must replicate its genetic material (except in Meiosis II).

Chromosomes must replicate so that both cells that are formed from cell division can have the same genetic material.

Each daughter cell must have a copy of the full cellular genetic material or there would be no reason for mitosis. Once the cell gives rise to two daughter cell it is too late to replicate the genetic material then.

For a virus to replicate it must insert its own DNA into a host nucleus cell. This newly infected cell finds another host cell to replicate, and a viral infection is produced.

DNA must replicate itself before mitotic cell division so that the two new daughter cells have the same amount of DNA, and identical DNA.

The DNA only needs to replicate if the cell is going to divide. In a dividing cell the DNA must replicate in order to provide a complete copy of the genome to each new cell.

Before a cell can reproduce, it must first replicate, or make a copy of, its DNA.This is so that when it divides, each of the daughter cells will receive a copy of the DNA.

Replication of DNA is preceded the cell division. During cell cycle a trigger for cell nucleus to undergoing division is received and the cell enters for division.

before cell devision the cell must undergo cell cycle

cells must copy their DNA to replicate

Cell Division: A cell must go through Interphase, where the cell prepares for division, and makes a copy of its DNA. It then goes on to Mitosis, which has 4 stages (prophase, metaphase, anaphase, and telophase) during which stages it basically sends on its copies of DNA (chromosomes) to the daughter cells. Then it goes on to Cytokinesis where the cell finishes splitting into two daughter cells, and the chromosomes are equal to the parent cells before Cell Division...

they must find a host cell in the infected body and take it over to force it to replicate

Before the cell can divide, there are several things that must happen. # The cell must grow twice its normal size # All the chromosomes must divide. # All the organelles must divide. # Mitosis (division of the nucleus). Now the cell is ready to divide.

No. Viruses must invade a host cell and hijack its resources to replicate itself.

DNA must replicate before mitosis can begin. Mitosis is another word for cell division and so there needs to be two copies of the DNA for the two new cells.

Cell division must be controlled to replace dead cells. Too many cells, or a buildup of cells, is what causes cancer.

before cell division happens after the old tissues have to be renewed or repaired.

A mother cell, or a gamete must have chromosomes that have replicated. Any parent cell must replicate their chromosomes, forming two sets of sister chromatids. This is known as a diploid cell. A cell must be healthy, with functioning centrioles, undamaged chromosomal DNA.

Multicellular organisms must replaced damaged cells. The only way to do this is through cell division.

The cell must have sets of chromosomes with DNA. When they are separated, the new cell has an exact copy of the DNA from the original cell.

Cell division has to occur in order to replace dead cells and keep the body functioning. This must be controlled because unmitigated cell growth is called cancer.

Each cell needs to have DNA in it in order to function (with the one key exception of a red blood cell which has no nucleus). In order to make sure each copy of the cell that is produced during cell division has the necessary information to function,the DNA must first be replicated and then each of the cells gets one copy of the DNA.
