Answer:
If the DNA wasn't duplicated, one of the daughter cells wouldn't have DNA and die.
Explanation:
The cell would split into a cell that had DNA and would survive and a cell that wouldn't survive. The one that doesn't have DNA wouldn't be able to go through cellular functions. Why? The DNA needed to direct functions wouldn't be present.
It is important that the cells DNA is duplicated before cell division, because it guarantees the availability of a copy of the genetic information contained in the stem cells for each daughter cell.
In DNA duplication, an original double-stranded DNA molecule is converted into two identical daughter DNA molecules.
DNA replication requires the presence of complex cellular proteins that direct a particular sequence of events.
When replication begins, the two chains unwind and separate from each other in a small segment of the molecule.
Free nucleotides present in the cell's cytoplasm bind to the exposed bases of the exposed single-stranded DNA fragment of the original molecule.
DNA duplication before cell division must be carried out with high copy fidelity, that the base sequence of the daughter molecules is exactly the same as that of the stem cells.
The transfer of genetic information from parents to children guarantees the succession of life and conservation of the species, since the descendants always have structural and functional characteristics similar to the parents.
This transfer of information from a cell or an organism to its descendants has its molecular basis precisely in the duplication or replication of deoxyribonucleic acids.
Therefore, we can conclude that it is important that the cells DNA is duplicated before cell division, because it guarantees the availability of a copy of the genetic information contained in the stem cells for each daughter cell.
