Chromosomes have to be duplicated so that the same amount of DNA will be transferred into the new cells formed by mitosis. The new cells will be mutated if they do not duplicate.
In Breaking Dawn by Stephenie Meyer, a wolf is said to have 100000000000 chromosomes, but in answer to the question, "How many chromosomes does a wolf half?" on this site, they are said to have 20000000957848937574836583645847.
Transcription must occur .
A casting in dentistry is disinfected before and after a person trys-in. The casts must be disinfected as they are how molds are created for people's teeth.
Before eating again, an owl must regurgitate pellets which contain indigestible parts of their prey, such as bones, fur, and feathers. This helps to clean out their digestive system and make room for new food.
Parasitic wasps lay their eggs among the eggs of aphids. There must be aphids already present so that the wasps can lay their eggs and the wasp larvae will infect the aphid larvae.

Telophase is a phase of mitosis. DNA replication must occur before mitosis begins. If it does not then the DNA chromosomes may not be consistent throughout the division of the cells.
After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
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.
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.
Chromosome duplication ensures that each daughter cell receives a complete set of genetic information. This process also helps to maintain the proper chromosome number in the daughter cells after cell division. Duplicate chromosomes allow for accurate segregation of genetic material during mitosis, ensuring that each daughter cell receives a copy of every chromosome.
DNA replicates and forms tetrad—APEX.
Cells must copy their chromosomes before mitosis to ensure that each daughter cell receives a complete set of genetic information. This process, known as DNA replication, ensures that the daughter cells will have the same genetic material as the parent cell. Without this replication, the daughter cells could end up with missing or incomplete chromosomes, leading to genetic abnormalities.
Each daughter cell will also have 12 chromosomes after mitosis. Mitosis is a process of cell division where the genetic material is replicated and divided equally between the daughter cells, maintaining the same number of chromosomes as the parent cell.
A cell undergoing mitosis has twice the usual number of chromosomes for that species. For example, human body cells have 46 chromosomes, but after DNA replication, which must occur before mitosis, a human body cell will have 92 chromosomes.
S phase must come before mitosis because during S phase, DNA replication occurs, ensuring that each new daughter cell receives a complete set of genetic information. Without DNA replication in S phase, the daughter cells produced during mitosis would not have the correct amount of genetic material needed for proper cell division. This would result in genetic abnormalities and potential cell death.
