They must unwind part of the original DNA molecule.
Unwind part of the original DNA molecule :)
Before replication can begin, the parent cell must undergo a period of growth and DNA must be duplicated during the S phase of the cell cycle. Additionally, the cell must ensure that all necessary molecules and enzymes required for replication are available.
A duplication of the chromosomes is what must happen before meiosis can begin.
Before DNA replication can take place, the DNA molecule must unwind and separate into two strands, a process catalyzed by enzymes. This separation into single strands allows for the complementary base pairing to occur during replication. Additionally, a primer made of RNA is needed to initiate the process by providing a starting point for DNA polymerase to add nucleotides.
Before the two strands of a DNA molecule can separate during replication, the hydrogen bonds holding them together must be broken, and the double helix structure unwound by enzymes such as helicase. This allows the DNA polymerase enzyme to move along each strand and synthesize complementary new strands.

Before DNA replication can occur, the DNA double helix must unwind and separate into two strands, a process facilitated by enzymes such as helicase. Additionally, the enzymes primase and RNA primer must synthesize short RNA primers to provide a starting point for DNA polymerase. These steps ensure that the DNA strands are accessible and ready for the addition of new nucleotides.

DNA replicates and forms tetrad—APEX.
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
Before meiosis can begin, the cell must undergo a process called interphase, specifically during the S phase, where DNA replication occurs. This ensures that each chromosome is duplicated, resulting in sister chromatids. Additionally, the cell must prepare by accumulating the necessary proteins and organelles required for the meiotic process. Once these conditions are met, the cell can enter meiosis, starting with prophase I.
