DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!
Why is DNA replication important for reproduction?
It is important for reproduction. Replication of a DNA is a very basic process that should happen within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. Hope this answers the question.

What happens to the daughter cells during mitosis?
During mitosis, a cell divides into two identical cells referred to as daughter cells. In order for both cells to be fully functional and to be able to mature, they each need a complete set of DNA. To prevent the mutations and errors in the DNA, the process has to be extremely accurate.
How does DNA replication work?
The DNA replication process not only has to be completed before this point, but the DNA has to be wound back up and the two copies of the same chromosome (now connected at a point in the chromosome) have to get in position so that they can be pulled apart, each destined for its new cell.
Why does DNA replication occur before mitosis?
This process has to occur before mitosis because once mitosis starts, the cell is already preparing to divide. Soon after it begins, microtubules are forming in order to separate the newly replicated chromosomes. The DNA replication process not only has to be completed before this point, but the DNA has to be wound back up and the two copies of the same chromosome (now connected at a point in the chromosome) have to get in position so that they can be pulled apart, each destined for its new cell.
What is the name of the process where a cell divides into two identical cells?

Why does DNA strand break in mitosis?
This process has to occur before mitosis because once mitosis starts, the cell is already preparing to divide.
How many errors does DNA copying have?
To prevent the mutations and errors in the DNA, the process has to be extremely accurate. Usually the error rate for copying DNA is around 1-3 errors for every billion base pairs. To get this extremely exact method of copying, there are many checks that happen within the process.
Why do microtubules form before mitosis?
Soon after it begins, microtubules are forming in order to separate the newly replicated chromosomes.
