DNA replication occurs once during mitosis. Replication also occurs once during meiosis even though there are 2 divisions that happen.
the DNA replicates before mitosis begins
Cells replicate for many reasons, they replicate by a process of mitosis or meiosis. Mitosis producing two daughter cells and meiosis producing gamete cells (sperm or ovum(egg) )
The DNA replicates before mitosis begins
mitosis
because the DNA cannot leave the nucleaus. so it creates a duplicate of the DNA so the process of mitosis can carry out

no DNA replicates before mitosis. It replicates in the S phase of inter phase

Because mitosis needs new DNA to continue If you think about the order mitoses goes throw it makes more since.
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.
mitosis is the process by which the DNA of a cell is copied, so chromosomes replicated throughout the process
Replication
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)
There are five stages of mitosis, beginning with interphase and ending with telophase. Interphase is the longest phase, during which the centrioles and DNA replicate and preparations are made for mitosis to occur.
