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.
DNA makes copies of itself
S phase - for synthesis
DNA is duplicated though a process called DNA replication. It is a process which involves many enzymes (proteins with specific functions) interacting with the parent DNA strand and creating a copy of it. DNA replication is called semi conservative because in the newly formed DNA, one strand belongs to the parent strand and the other one is synthesized newly.
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.

Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)

A nice simple answer for you: Replication.

something to do with dna

The enzyme
DNA makes copies of itself through the process of replication. Because the nucleotide bases are complementary, they automatically make the other strand of complementary bases when the division of the cell occurs.
