Here's why:
* DNA Contains Genetic Information: DNA holds the blueprint for an organism's development and function. This includes instructions for building proteins, regulating gene expression, and determining cell fate.
* Clones Share Identical DNA: Cloning involves creating a genetically identical copy of an organism. This means the cloned cells and the original organism have the same DNA sequences.
* DNA Determines Cell Specialization: During development, cells specialize into different types (e.g., muscle cells, nerve cells, etc.) based on the genes that are expressed within their DNA.
Therefore, the DNA of the original organism dictates the development of the cloned cells and ultimately determines which cells will be part of the clone.
While other factors play a role in development, DNA is the fundamental blueprint that guides the entire process of cell division, specialization, and ultimately, the formation of a complete organism.
