Well, sweetheart, cells duplicate their DNA before diving into mitosis or meiosis because they need to make sure each daughter cell gets a full set of genetic instructions. It's like making a copy of the recipe before you start baking - you wouldn't want to mess up the cake by missing an ingredient, now would you? So, DNA duplication ensures that each new cell gets its own complete set of genetic material to carry on with its own sassy self.
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
The cell must undergo DNA replication to ensure that each daughter cell will receive a complete set of chromosomes during meiosis or mitosis. This step is crucial for the accurate distribution of genetic material to the daughter cells.
Mitosis occurs first in the cell cycle before meiosis.
The interphase occurs before both mitosis and meiosis. During interphase, the cell grows, carries out normal metabolic activities, and duplicates its DNA in preparation for cell division.
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
In meiosis, the phase that is typically skipped or shortened compared to mitosis is interphase. This is because the DNA does not need to replicate again before entering meiosis II, unlike in mitosis where each cell cycle is followed by an interphase for DNA replication.

Chromosomes duplicate in a process called mitosis.
The interphase occurs before both mitosis and meiosis. During interphase, the cell grows, carries out normal metabolic activities, and duplicates its DNA in preparation for cell division.
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. :)
DNA is replicated during the S phase of the cell cycle before both mitosis and meiosis.
Chromosomes duplicate during the S phase of the cell cycle, which occurs after DNA is replicated and before cell division (mitosis or meiosis). This ensures that each daughter cell receives a complete set of chromosomes with identical genetic material.
Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
Replication does not take place during mitosis. It takes place before meiosis begins.
