What copies the DNA in the cell cycle?

DNA is replicated in the Synthesis stage of the cell cycle.


How many copies of DNA does each cell have in the human body?

Each cell in the human body typically contains two copies of DNA.


When the cell has not yet gone through mitosis does the cell do anything to the DNA?

The DNA makes copies of its self.


Why is it necessary for a virus to invade a living cell to make copies of itself?

Since viruses are nonliving they have to invade and hijack a living cells DNA to make more copies of itself. If it cannot do this it cannot make more copies of itself.


Does a cell increase in size and usually makes copies for its DNA?

True.When a cells size increases,it can't transfer enough nutrients throughout the cell if the cell size is big.So it makes copies of its DNA


What is the process by which a cell makes a copy in meiosis?

Before meiosis begins, the cell copies its DNA in the process of DNA replication.


Why does DNA make copies?

as cell divides the DNA also hav to divide to b transfferd in to newly formed cell so for that DNA divides


What is the specific process during which the cell copies its DNA?

Well a virus can duplicate many copies of itself by attaching itself to a cell, any cell, and using the cells machinery they inject their DNA and later the cell bursts and copies of the virus come out. When a bacteria duplicates it uses binary fission. Binary fission is when a bacteria splits itself into two and makes to copies of itself. Hope I answered your question.


True or false cell increases in size it usually makes extra copies of its DNA?

A cell does not make "extra copies" of DNA. Through a persons life, DNA can only be copied so many times. The only time DNA does "copy itself" would be if a new cell is needed. For example, your skin cells die all the time and are shedded off from your skins surface. Your skin then is going to get to the point where more cells are going to be made. The DNA replicating process is what starts the process of cell mitosis (making more cells). All the DNA in your body is used, so a cell does not make extra copies of DNA. If the DNA gets destroyed, that cell dies and is replaced by another.


What is copies during replication?

A cell's DNA is copied during replication.


How does a virus multiplied?

A virus injects its DNA into the host cell making it produce multiple copies of that DNA and multiple copies of the protein capsule of that virus. After a while, the host cell becomes full of many copies of that virus, then the host cell explodes releasing all the new viruses. If the host cell is a bacterium and the the virus is a bacterophage, this phenomenon is done in two ways either by the lytic cycle in which virus DNA survives and the bacterial cell is destroyed,or the lysogenic cycle in which virus DNA is incorporated in the host cell DNA.


When a cell grows what phase copies its DNA and gets ready to divide?

Its called cell division
